Honors Physics Unit 6: Momentum and Collisions

Front

What is the formula for Force?

Back

Force = mass × acceleration (F = ma)

Front

What law states that Force equals mass times acceleration?

Back

Newton's 2nd Law

Front

What happens to the momentum of an object when its speed is doubled?

Back

The momentum doubles.

Front

What type of collision involves objects bouncing off each other?

Back

Elastic collision

Front

In an elastic collision, what happens to the kinetic energy?

Back

Kinetic energy is conserved.

Front

What is the formula for momentum?

Back

Momentum = mass × velocity (p = mv)

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision equals the total momentum after the collision.

Front

What is an inelastic collision?

Back

A collision where objects stick together and kinetic energy is not conserved.

Front

If a 3,000 kg truck moving at +10 m/s hits a 1,000 kg parked car and the car moves off at +15 m/s, what is the final velocity of the truck?

Back

5 m/s

Front

What effect do softer landings have on impact force?

Back

Softer landings increase collision time.
