Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

sample The second law states that the net force on an object is equal to the rate of change (that is‚ the derivative) of its linear momentum p in an inertial reference frame: [pic] The second law can also be stated in terms of an object’s acceleration. Since the law is valid only for constant-mass systems‚[16][17][18] the mass can be taken outside the differentiation operator by the constant factor rule in differentiation. Thus‚ [pic] where F is the net force applied

The conservation of momentum can be a huge effect on the cars‚ so the conservation of momentum states that when there are no other outside forces like friction the total momentum of the objects interaction does not change. The amount of momentum before and after the collision will be the same. If this is the case then the momentum of the first car‚ mass times velocity‚ does not change the momentum of the second car if the second car is at rest so the second car would have the same momentum as the

(5M) Put a coin and a small paper disc in a glass tube (1M) Use a vacuum pump to remove the air from the tube (1M) Hold the tube vertically then invert it quickly. (1M) The coin and the paper disc fall at the same rate (1M) The experiment shows that objects with different masses fall at the same rate when there is no air resistance.

of the various safety precautions taken. Because when an object stops‚ or is stopped by a collision‚ the same change in momentum occurs no matter the size of the force or the time interval‚ these sheets of metal are critical to the passengers safety. The metal sheets not only absorb energy from the oncoming vehicle‚ but they also slow it down; and because the change in momentum is equal to the impulse‚ the longer it takes for a force to reach the passenger‚ the smaller the force will be. Another

Hint: Energy variables are capital Momentum proportional to mass and velocity p=mv Units= kg time m/s And is vector in as direction as velocity Conservation laws are applied in closed systems only Collisions are closed Momentum is conserved///// total energy is conserved Momentum always conserved in collisions thus collision problems are aways momentum problems Total energy is always conserved Types of collisions: Elastic collisions Kinetic energy

band-powered car that demonstrates Newton’s laws‚ and conservation of energy. The advantages of having a heavy rolling can is that I would have a lot of rotational energy and momentum‚ the disadvantage is the car has more static inertia. If the car has more static inertia‚ then it will be harder for the can to roll backwards at the end of its run. The factors affecting the can’s net force (once the rubber band is unwound‚ but when the car still has momentum) are‚ force of gravity‚ normal force‚ KE‚ rubbing
