Question
Please I need help with my Physics Lab analysis question. I need a full explantion of every answer because this is a lab report.
Subject is Momentum and Collision.
Q.1:What happens to the objects, the momentum and the mechanical energy in an elastic collision? What happens to the objects, the momentum and the mechanical energy in a completely inelastic collision?
Q.2:In each trial, what happens to the momentum (compare before and after)? Does each of your results confirm the Law of Conservation of Momentum? Explain how you arrived at your conclusions. Discuss one significant source of error in the experiment.
M1 and M2 is the mass of the cart. in trial 2-3 we added wheight to the cart.
Vi is the initial velocity.
Vf is the final velocity.
P is the momentum 1 before 2 after collison.
ke is kinetic energy.

Q.1:What happens to the objects, the momentum and the mechanical energy in an elastic collision? What happens to the objects, the momentum and the mechanical energy in a completely inelastic collision?
In Elastic Collision,
Momentum remains conserved .
Kinetic Energy remains conserved.
In Inelastic Collision,
Momentum remains conserved, but
Kinetic Energy does not remain conserved.
Momentum is not conserved in any of the trial, which can be seen clearly as value before collison p1, and after collision p2 is not same. Therefore Law of Conservation of Momentum is not valid .
