Chapter 6 Test Flashcards
A quantity defined as the Product of the mass and velocity of an object.
Momentum
The product of the force and the time over which the force acts on an object
Impulse
Momentum is mass times velocity
Momentum is mass times velocity
A change in momentum takes force and time.
A change in momentum takes force and time.
Stopping times and distances depend on the impulse-momentum the room.
Stopping times and distances depend on the impulse-momentum the room.
Force is reduced when the time interval is an impact is increased
Force is reduced when the time interval is an impact is increased
Momentum is conserved in collisions.
Momentum is conserved in collisions.
Momentum is conserved for objects pushing away from each other.
Momentum is conserved for objects pushing away from each other.
Newton’s third law leads to conservation of momentum.
Newton’s third law leads to conservation of momentum.
Forces in real collisions are not constant during the collisions.
Forces in real collisions are not constant during the collisions.
A collision in which two objects stick together after colliding
Perfectly inelastic collision
A collision in which the total momentum and the total kinetic energy are conserved.
Elastic collision.
Perfectly inelastic collisions can be analyzed in terms of momentum.
Perfectly inelastic collisions can be analyzed in terms of momentum.
Kinetic energy is not conserved in elastic collisions.
Kinetic energy is not conserved in elastic collisions.
Most collisions are neither elastic nor perfectly inelastic.
Most collisions are neither elastic nor perfectly inelastic.
