Investigative Question:
During a collision between two objects, is the amount of momentum present in a system before the collision different to the amount of momentum present afterward or is the total momentum of the system conserved.
Aim:
To prove that law which states that the total momentum present in a system is conserved is true.
Hypothesis:
Although the mass and the velocity of the moving object will be altered during the collision, the proportion of the alteration should be such that the total momentum present in the system will be conserved.
Apparatus:
1. Ticker Timer
2. Ticker tape
3. Ramp
4. High table
5. 2 thick textbooks books
6. 2 mass pieces
7. string
Method:
1. Place the ramp on a regularly high platform (ensure that the ramp is about 1.7m above ground)
2. Place the textbooks beneath the ramp at one end to incline the ramp slightly so that the trolley can overcome friction.
3. Attach a strand of string onto the foremost part of a trolley and attach the other end of the string to a mass piece.
4. Suspend the mass piece off the foremost part of the ramp and hold the trolley on the inclined end.
5. Attach ticker tape to the end of the trolley (opposite to side where the string is attached).
6. Feed the ticker tape through a ticker timer and switch the timer on.
7. Suspend a mass piece halfway between where the trolley will be let go and the end of the ramp.
8. Let the trolley go and drop the mass piece on the trolley when the trolley is exactly below the mass pi...

...ties before and after the collision are calculated using the times obtained from the electronic timer. This method is more gives a more precise volume then the ticker tape method, because the factor of human error in analysing the tape is eliminated. (Mann 2013)
Conclusion:
After the collision, both the mass and velocity of the object changed but the total momentum present in the system was not conserved.

Toyota Sienna comes with the “in-floor” system that VMI is known for. As opposed to a "fold-out"-style ramp, the in-floor unit is placed between the passenger floor and the bottom of the vehicle. The main advantage of an in-floor ramp is that it doesn't intrude into the passenger area of the van when stowed, which leaves more room for the passengers. Additionally, it protects the vehicle from moisture. This controls system is very easy to use and there are three buttons that will open the passenger-side sliding door and deploy the ramp at the same time: one on the keyfob, the other near the door in the rear passenger area, and one on the vehicle's center....

An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision.

The momentum of an egg dropped into a frying pan at shoulder height is going to be the m x v (mass times velocity). This is going to be the same whether you drop the egg into a frying pan, into a bucket of water, or onto a pillow. The impulse in the egg drop report is the force of the egg multiplied by the time. This is when the egg is in contact with the object and the time that it stays their. When the eggs bounced of the pillow we see a greater change in momentum. We see the momentum come to a stop, but the momentum changes directions. The change in momentum is calculated by multiplying force times time.
Isaac Newton discovered gravity when an apple had fallen on his head. He then began to think about how the apple had fallen onto his head and thus Newton’s three laws of motion were created. Newton’s first law of motion is an object in motion tends to stay in motion; an object at rest tends to stay at rest, unless another force is acted upon it. Newton’s second law of motion is about the formula for force, which is force= mass*acceleration. Newton’s third law of motion is for every action there is an equal and opposite reaction. Furthermore, Isaac Newton created the three laws of motion.
Here mass, acceleration, momentum, and force are the quantities that are defined externally i.e. they are the externally defined quantities. It is also equally true that Newton’s laws of motion do not suffice to characterize the motion of deformable and rigid bodies. After the generalization of the laws of motion propounded by Newton in 1950 by Leonhard Euler, the laws were equally accepted for rigid bodies, and this was later called as Euler's laws of motion. This theory was later applied in the deformable bodies, and the laws were equally true in that condition, as well. Even though this law is outmoded by laws of relativity, this law is equally applicable in the situation where the speed of objects are less than the speed with which light travels.
This experiment could have been more accurate if the angle of the slope could have been lowered to stop the trolley from accelerating. The experiment could have also been improved by taking greater care in making sure that the weights didn’t fall off of the trolley after they collided with the trolley. Better weights should have been found for the 1.5kg as the ones used had to be tied together to reach the sufficient weight, thus making them more likely to fall off the trolley. Conclusion: The hypothesis was proven correct for the 500g weight, however, the hypothesis was not proven correct for the 1kg and 1.5kg weights as the momentum before the collision did not equal to the momentum after the collision.
-The masses, distances and times will be measured in order to calculate the momentums of the systems before and after collision occurs.
Different collisions took place throughout the process of the Rube Goldberg Machine. This included Elastic and Inelastic collisions. An example of an Elastic Collision in our Rube Goldberg Machine is when the car went down the track and collided with another car. Elastic collisions are defined as collisions with conservation or no loss of momentum. This is proven by the first car which transferred its momentum to the second car thus momentum was perfectly conserved. An Inelastic Collision is seen in our project ...

The object was created by Sir Isaac Newton to demonstrate conservation of momentum of energy through five swinging spheres. When one end of the device is lifted and then released it strikes the other spheres and the direct force causes them to move. The first ball might have caused the impact but it was not capable of moving itself and another sphere did not move it. The force that created the initial reaction was outside of the Newton’s cradle. Newton however had a very different outlook on motion “The Newtonian motion which remained, however, is the result of conflict, lacks any purpose or goal and has nothing to do with the divine life itself. Aristotle, and indeed Plato before him, would have viewed such motion” (SIMON OLIVER) Even though both famous academic thinkers came to the same conclusion that everything in motion must have be placed in motion they cannot come to the same conclusion “Ultimately, all motion is seen as a participation in the most perfect "motionless motion" of the Trinitarian Godhead in which all things are known, and thereby created and sustained, in the eternal emanation of the Son from the Father. By contrast, Newton outlined a view of motion which saw this category as a primitive state to which bodies are indifferent. Thus motion tells us nothing about the ontology of creation.
Isaac Newton was an English physicist and mathematician and is now considered a widely recognised scientist because of the work that he did by contribution to scientific knowledge. He is known for creation 3 laws of motion that have stood correct for three centuries.
This law is one of the most popular and well known laws of the three. For an easy example you could be stepping off a skateboard toward the ground, we end up pushing the skateboard backward, an easy everyday activity. This is one of Newton’s greatest accomplishments; these three laws. They have extremely helped us in physics, science, and mathematics. Without these laws we wouldn’t be where we are today....
