Inclined planes are yet another simple machine that you use nearly every day. Any time you walk up a slight hill, you are using an inclined plane. Any time you ride your bike or drive your car up a hill on the way to school, you are using an inclined plane. Even when you push your grandma in her wheel chair up the handicap ramp you are using an inclined plane. So to summarize what an inclined plane actually is, it is a flat surface on an angle that is always used to multiply your force. BUT WAIT! You, Mr. Davis, and I both recently learned that that statement ISN'T always true. You concluded while watching the Olympics that snowboarding ramps aren't force multipliers, but speed multipliers. All inclined planes that are force multipliers have a length longer than their height. However, with snowboarding landing ramps, especially during the snowboard cross event, the big jumps have heights longer than the lengths. For IMA in inclined planes, you divide the length by the height, so when this scenario occurs, an IMA of less than one occurs which indicates a speed and displacement multip...
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.
11. What is the difference between a. and a. Place more books underneath the raised end of the ramp. increase the height at the summit by 10cm. Use the metre stick to

I am now a professional snowboarder with my friends at Mammoth Mountain, the local resort, anxiously preparing for the X- Games slopestyle competition that is a few days away. The slopestyle competition that I am competing in is a snowboarding course that consists of rails and jumps that are
In the novel Ragtime, many aspects of the American society are explored. The reader gets an understanding of the history and hardships of different social classes, races, and cultures during the last century. A persistent theme established is the existence of the American dream. Doctorow expresses his fascination of the social mobility since it includes the impoverished and underprivileged. However, he highlights that when attempting to reach success, one is required to make sacrifices, negotiating his morality and identity. Tateh and Coalhouse are crucial examples of how the demands, prejudices, and opportunities of the American society can change a man’s mentality.
Lift is a simple concept to grasp, yet the reason it exists is a complex one. To this day there is still great debate over what is the cause of lift. There are several popular explanations given which are commonly found in student textbooks, and even pilot training manuals, yet these popular explanations do not stand up to serious physics analysis. The most common of these arguments is based off of Bernoulli’s Principle.
As a simple case, consider the simulation of document . In the frictionless case, the only force acting on the skater is gravity. Therefore, according to the conservation of energy, the sum of the kinetic and the potential energy remains constant. As the skater climbs the ramp, his height increases. According to document , as the skater’s potential energy is proportional to his height, the skater’s potential energy increases. However, the skater’s velocity also decreases as he climbs the ramp. Again, according to document , as the skater’s kinetic energy is proportional to his velocity squared, the skater’s kinetic energy decreases. The interplay between these two energies is such that their sum remains constant and the law of conservation of energy remains
The NASA Crane Project was a project in which we designed a crane out of cardboard and pencils and attached a cup with string to the end. The goal was to lift as many batteries as possible in the cups. You were not allowed to touch the cups and the only way that you could lift them was via a string that was wrapped around a pencil at the back of the crane that was twisted. Only 30 batteries could be in each cup, and to have more batteries you had to add more cups.
The summation of force helps you with your performance in sport. This method aids your actions amidst the game, and improves your hits, throws and pushes by joining all your energy from your muscles
A trebuchet is a siege device that was used in the wars and sieges of the Middle Ages. It is used to either smash masonry walls or to throw projectiles over them. It is sometimes called the “counterweight trebuchet” in order to differentiate it from an earlier weapon that has come be to be called the “traction” trebuchet, the original type with pulling men instead of a counterweight.
Do you currently suffer from mobility issues, and require more than just a wheelchair for assistance? Have you found that going up and down the stairs of your home is becoming increasingly difficult? If this sounds like you, you may be interested in a pitless elevator lift. A pitless elevator lift can be used by anyone, not just those that suffer from chronic mobility issues. In this article, you will learn about the many benefits of having a pitless elevator installed in your home,
Sledding isn't just taking a board and skyrocketing down a hill. If you're looking for some science and money saving, you should make your own board Different sizes, materials, and shapes will show how a simple change works with friction and gravity. not only that, but a sled and a hill pretty much makes your own private roller coaster in your backyard, Just put some obstacles and you set. Also, you can go on different hills that will fit your speed.. Feeling brave? Go on a large hill. But if your skills aren't sharp go for a little kiddie hill. Overall , sledding is an adventure you will never
from operation, and act as a shock absorber if the robot is struck by an object or dropped.
Snowball wanted to build the windmill so it could operate a dynamo and supply the farm with electricity. Which would light and warm the animals. Of course Napoleon declared himself against the windmill from the start (49). Napoleon was so against the plans he urinated on the plans and then he walked out like nothing had even happen (50).
Imagine an angry hive of bees. Now, put that under the hood of the beautifully curvy body of a mid 90s Japanese sports car and crank the revs up to 9000. The rotary engine, a Mazda classic, is one of the most satisfying, temperamental,and rev happy engines of all time. The Wankel/Rotary engine is an internal combustion engine that uses an eccentric rotary design to convert pressure into rotating motion. Instead of the more common reciprocating piston designs, the Wankel engine has the advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio primarily because three power pulses per rotor revolution are produced compared to one per revolution in a two-stroke piston engine and one per two revolutions in a four-stroke piston engine.
