Unit 3 Ticket to Retake (Conservation of Momentum)

Front

What does the Law of Conservation of Momentum state?

Back

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

Front

What is the equation that enforces the principle of conservation of momentum?

Back

mv = m₁v₁' + m₂v₂'

Front

What is the purpose of crumble zones on a car?

Back

To increase the time of impact.

Front

What is the unit for momentum?

Back

kgm/s

Front

If each object is moving at the same velocity, which will have the least momentum?

Back

Golf Ball

Front

Define momentum in physics.

Back

Momentum is the product of the mass and velocity of an object, represented as p = mv.

Front

What is the formula for calculating momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

Explain the concept of impulse.

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

What happens to momentum in a closed system during a collision?

Back

Momentum is conserved; the total momentum before the collision equals the total momentum after the collision.

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.
