Why is more impulse delivered during a collision when bouncing occurs than during one when it doesn't?
Bouncing collisions involve objects rebounding off of each other with some degree of elasticity, while non-bouncing collisions involve objects coming into contact and sticking together.
In bouncing collisions, the impulse delivered is greater and the duration of the collision is shorter, resulting in a larger change in momentum for the objects involved. In non-bouncing collisions, the impulse delivered is smaller and the duration of the collision is longer, resulting in a smaller change in momentum.
The impulse delivery in a collision is affected by the mass, velocity, and elasticity of the objects involved. A heavier object will deliver a larger impulse, while a faster-moving object will deliver a larger impulse. The elasticity of the objects also plays a role, as a more elastic collision will result in a larger impulse.
The coefficient of restitution is a measure of the elasticity of a collision, with a value of 1 indicating a perfectly elastic collision and a value of 0 indicating a completely inelastic collision. In bouncing collisions, the coefficient of restitution is greater than 1, while in non-bouncing collisions, the coefficient of restitution is less than 1.
Bouncing collisions result in a transfer of kinetic energy between the objects involved, with some energy being lost due to friction and other factors. Non-bouncing collisions, on the other hand, typically result in a decrease in kinetic energy as the objects stick together and lose their individual velocities.
