In this essay, I will be describing my Rube Goldberg machine and how it relates to force, motion, speed, and the transfers of energy through each step. In this project, we have a series of drops turns and transaction where one object will hit another. The goal of our machine is to pop a water balloon. To pop the water balloon we had a track that led to the water balloon hitting a mouse trap and popping it.
At the beginning of our machine, the golf ball has gravitational potential energy. It is not in motion but as soon as we cut the string the first golf ball will start to roll down the ramp. This will convert the gravitational potential energy into mechanical kinetic energy. This transfer of energy made the ball start to move and speed up

as it goes down the ramp. The speed of the gold ball ball depended on its mass. If the mass would change we would have might have had to change something about our project. The speed of the ball would have changed if we would have chosen a bigger or smaller ball. Friction started acting on the ball as soon as it started moving. As it rolled down the ramp, rolling friction started acting on the ball in the opposite way the ball was going. The next step in our machine was the first golf ball hitting the second one and sending the second gold ball onto the second part of our machine. The first ball’s energy was transferred to the second one causing it to move. As an individual, the second golf ball already has gravitational potential energy and is waiting for an outside force to get it moving. Once the ball is hit it sends the second ball into motion causing it to still have gravitational potential energy and mechanical energy. If the mass of the one or both balls were to change, the speed would change causing a different result to the one we have already gotten. The ball would have either not had enough force to get it to actually get moving through the machine or it would go so fast it would ruin the steps after it. Again, once the second ball started moving friction was acting upon it. The type of friction that acted upon it was rolling friction. As for the first ball, friction stopped the ball from continuing. As the golf ball continues onto the next step, it reaches the drop-off point.
Here the golfball will fall and land into another area to keep it going. When it drops off, the amount of gravitation potential energy decreases as a result because it is falling closer towards Earth. As it falls, some of the energy is transferred into thermal energy. As it falls, it accelerates. The mass of the golf ball affected the acceleration because if we were to have a had a larger or smaller ball the acceleration rate would have increased or decreased depending on the size off the ball. As the ball fell, the friction that acted upon it was different from the other steps. When the ball fell, fluid friction acted upon it because when an object falls or moves through a liquid it is created. In this situation, the golf ball is falling through the atmosphere. Once the ball lands on the other track, it accelerates down the track. Rolling friction occurs as well here. The stored gravitational potential energy is turning into mechanical and kinetic energy. Once the ball reaches the end of that point, it zooms across an empty space and lands in another turn track. Through that transaction, again gravitational potential energy is being turned into mechanical energy as it falls. Speed affected this part because if the golf ball was not going fast enough it would have not made it to the turn part. If the speed was faster, the golf ball would have overshot and missed the turn track. Since friction always occurs, the friction here was fluid friction. Again, this is because it is falling through the atmosphere. Once the ball reaches the track, that friction is changes into rolling
friction. Now, the golf ball turns and reaches another track where it goes down at a steep angle. The gold ball will then hit the water balloon that is inside of the steep track. The water balloon will then be forced down along will the ball to hit the set mouse trap. As the ball drops, the energy is being turned form gravitational potential energy into mechanical energy. The type of friction acting on the ball is fluid friction because it is falling through the air. When the ball hits the balloon, there is a transfer of energy from the ball to the water balloon. Gravity helps in the process because it is pulling the golf ball and water balloon down. The friction on the water balloon is static friction when inside the tube, but when it reaches the outside part it is fluid friction. The balloon and ball both speed up at the drop off, causing both the balloon to start moving.
2. Now the belt is turning. This makes the secondary clutch turn, which causes the track to turn and the snowmachine to move forward.
Rube Goldberg is best known for his “Inventions” cartoons. Goldberg’s inventions show wacky, complex ways to complete somewhat meaningless tasks much like Seuss’s “inventions” in many of his books. A good comparison of the way that Goldberg may have influenced Dr. Seuss can be seen in Seuss’s famous book, The Cat in the Hat. On page fifty-six we see the Cat’s great machine that he uses to pick up his messes. The Cat shows a very complex way of picking up his “playthings”. The wonder...
Ever wondered how roller coasters work? It’s not with an engine! Roller coasters rely on a motorized chain and a series of phenomena to keep them going. Phenomena are situations or facts that have been observed and proven to exist. A few types of phenomena that help rollercoasters are gravity, kinetic and potential energy, and inertia. Gravity pulls roller coasters along the track as they’re going downhill. Potential and kinetic energy help rollercoasters to ascend hills and gain enough momentum to descend them and finish the track. Inertia keeps passengers pressed towards the outside of a loop-the-loop and in their seat. Gravity, potential and kinetic energy, and inertia are three types of phenomena that can be observed by watching roller
Although golfers end the day on the 18th green, their day begins on a tee box. A drive, the first hit off a tee toward the objective hole, may seem very routine and insignificant, but, in fact, it is the most important shot taken on each hole. If golfers hit a long drive into the nicely cut fairway, they have only to hit the ball off the nicely cut grass on usually a clear path to the hole. But if they hit a drive into the woods, then they have to make sure the ball does not hit any trees, branches, or other obstacles when exiting the woods. That’s why hitting a good drive is a must. With practice, even you can hit a fundamental drive.

We ran into Newtons First Law, which claims that an object resists change in motion, as the marble rolled down the floor it didn’t stop until it was acted against by friction. As we moved on, Newtons Second Law came into play when we were creating our lever as we need a ball that would roll down with enough acceleration that it could knock down the objects. Newton’s second law claims, that F=MA. So, we choose a golf ball since it would have more mass than a rubber ball, but it would have less acceleration when the lever was started. This way, it would knock the upcoming objects. Newtons Third Law claims that every action yields an equal and opposite reaction. This is proven in our Rube Goldberg Machine when the small car was rolling down the tracks as the wheels pushes against the track making the track move backwards. The track provides an equal and opposite direction by pushing the wheels forward.
By getting to this power point it leaves the maximum potential energy. That potential energy is put into kinetic energy and the ball is thrown, ...
The basic trimmer works by the engine driving a multi-bearing supported hardened steel shaft housed in an aluminium tube through a centrifugal clutch this shaft is connected to a “head” that holds a nylon line that spun at high revolutions per minute (RPM). This nylon line then cuts the grass by hitting the blades of grass at high speed, this cause the grass to be severed at the point of impact. Thus trimming the grass.
However another question still held, “Is inanimate and animate matter the same, or does it operate differently?” Adolf Eugen Fick and Max Rubner painstakingly tabulated the amount of energy required to contract muscles and other living requirements, to find that it was all equivalent to the energy consumed. Yet some people still believe that there is some great plan for us.
Explanation: The height of the ramp affects the speed and distance the ball rolls because the higher the ramp, the more gravitational potential energy the ball has, which is then transferred to kinetic energy. The length of the ramp affects the gradient, which affects the speed and distance the ball rolls. The surface of the ramp and marble cause friction, which affects the speed and distance the ball rolls. The weight and size of the marble affect the gravitational potential energy and the amount of friction, which affects the speed and distance the ball rolls.
Nature differs from innovation in an environment, such conflicts are presented in “The Pedestrian” and “The Flying Machine”. Leonard
Charles Alan Sylvestri’s poem “Leonardo dreams of hid flying machine” is a dramatic story of hope and optimism that takes the listener on a great adventure into the great unknown. Leonardo functions as the agonist of the poem who is “tormented” by his need to fly and touch the sky. Finally, after much planning and determination Leonardo takes a great leap of faith with his flying machine and his dreams of flight are consummated!
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
Introduction to Aerodynamics Aerodynamics is the study of the motion of fluids in the gas state and bodies in motion relative to the fluid/air. In other words, the study of aerodynamics is the study of fluid dynamics specifically relating to air or the gas state of matter. When an object travels through fluid/air there are two types of flow characteristics that happen, laminar and turbulent. Laminar flow is a smooth, steady flow over a smooth surface and it has little disturbance. Intuition would lead to the belief that this type of air flow would be desirable.
The file labeled “Newton’s 2nd Law” is to be opened. The cart’s mass along with the attachment of the sensor and the accelerometer are to be measured and recorded. Being carefully verified in order, the track is leveled and the Force Sensor is set to 10N and connected to...
