Momentum and Impulse Quiz

What is momentum?

• The force of gravity acting on an object

• The product of mass and velocity of a moving object

• The resistance of an object to change its state of motion

• The energy stored in an object due to its position

What is the formula for momentum?

• P = W / t

• P = m * v

• P = m * a

• P = F * t

What happens to the momentum of an object that is not moving?

• The force of friction between two surfaces

• The change in momentum of a moving object

• The energy lost during a collision

How is impulse related to momentum?

• Impulse is equal to the product of mass and velocity

• Impulse is the resistance of an object to change its state of motion

• Impulse is the change in momentum of a moving object
