Compare the velocities of both gliders before and after the collisions in each trial, How did the velocities change? If the masses were combined through inelastic collisions, yet momentum was conserved. How would you expect the velocity to change?

Explanation:

In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

An inelastic collisions occurs when two objects collide and do not bounce away from each other. Momentum is conserved, because the total momentum of both objects before and after the collision is the same. ... Some of the kinetic energy is converted into sound, heat, and deformation of the objects.

it doesn't. it was imagined up in the middle ages.

answer: a. same unit
