Momentum and Impulse Basics

Momentum is equal to:

• the product of mass times acceleration
• the product of force times distance
• 1/2 mv²
• the product of mass and velocity

Impulse is DEFINED as:

• the net force applied
• the net force applied multiplied by the time over which the force is applied
• the change in momentum of the object
• the change in energy of the object

An inelastic collision...

• is bouncy
• is sticky
• is one where momentum is not conserved
• all of the above answers are possible

An inelastic collision...

• is sticky
• is one where momentum is coserved
• is one where energy is not conserved
• all of the above are possible

Momentum is conserved AND energy is conserved in

• a perfectly inelastic collision
• a perfectly elastic collision
• either elastic or inelastic collisions
• none of the above

Momentum is conserved within a system...

• only when kinetic energy is conserved
• when there is a net external force applied to the system
• when the only forces applied to the system are within the system
• all of the above
