5th Six Weeks Checkpoint

Front

2 balls collide and bounce off of each other. During the collision total momentum remained constant and total kinetic energy remained constant. What type of collision is this?

Back

Elastic Collision

Front

A BMW rear ends a car at the stop light. Neither car sticks together. The momentum was conserved in the collision but the kinetic energy was not conserved. What type of collision is this?

Back

Inelastic Collision

Front

If a collision is elastic, what must be true?

Back

Kinetic Energy is conserved

Front

If there is a perfectly inelastic collision, which of the following must be true?

Back

The objects stick together after colliding

Front

Two carts collide and stick together. Is momentum conserved?

Back

Yes

Front

Is momentum conserved in an elastic collision between two metal balls?

Back

Yes

Front

What is the equation for momentum?

Back

Front

What is the momentum of a 2 250 kg Tesla going 15.0 m/s before the crash?

Back

33,800 kg m/s

Front

What word can best describe the total momentum in an isolated system?

Back

constant

Front

The Law of Conservation of Momentum states:

Back

The total momentum before a collision is equal to the total momentum after a collision.
