Momentum Study Guide

Multiple Choice

What is momentum?

• inertia in motion

• motion

• velocity in motion

• skibbidi toilet

Multiple Choice

how do you calculate momentum?

• Momentum is calculated by dividing an object's mass by its velocity.

  (m/v=P)

• Momentum is calculated by adding an object's mass to its velocity.

  (m+v=P)

• Momentum is calculated by multiplying an object's mass by its velocity.

  (P=mv)

• Momentum is calculated by subtracting an object's mass from its velocity.

  (m-v=P)

Multiple Choice

what is impulse?

• Impulse is the distance traveled by an object.
• Impulse is the speed of an object.
• Impulse is the force exerted on an object.
• Impulse is the change in momentum of an object.

Multiple Choice

what is elastic collision?

• An elastic collision is a collision where there is no change in kinetic energy.
• An elastic collision is a collision where there is a loss of kinetic energy.
• An elastic collision is a collision that happens without permanent damage & not generating much heat

  (also bouncy for example)

• An elastic collision is a collision where there is a gain of kinetic energy.

Multiple Choice

what is an inelastic collision?

• An inelastic collision is a type of collision in which both kinetic energy and momentum are conserved.
• An inelastic collision is a type of collision that when a collision happens then there is some sort of permanent damage & generates heat.

  (sticky)

• An inelastic collision is a type of collision in which momentum is not conserved.
• An inelastic collision is a type of collision in which only momentum is conserved.

Multiple Choice

what is the law of conservation of momentum?

• The law of conservation of momentum states that in order to change momentum, an impulse must be exerted.

• The law of conservation of momentum states that momentum is always increasing in a closed system.
• The law of conservation of momentum states that momentum is always decreasing in a closed system.
• The law of conservation of momentum states that momentum is only conserved in certain situations.

Multiple Choice

why does something bounce?

• Something bounces because of the gravitational force.
• the impulses are greater when an object bounces

• Something bounces because of the magnetic properties of the material it is made of.
• Something bounces because of the temperature of the environment it is in.

Multiple Choice

Inelastic collision formula?

• m1 (v1i )+ m2 (v2i)=

  (m1 + m2)v2f

• m1v1 + m2v2 = (m1 / m2)v
• m1v1 + m2v2 = (m1 * m2)v
• m1v1 + m2v2 = (m1 - m2)v

Multiple Choice

elastic collision formula?

• m1 (v1i)+ m2 (v2i)

  = m1 (v1f)+ m2 (v2f)

• m1u1 - m2u2 = m1v1 - m2v2
• m1u1 - m2u2 = m1v1 + m2v2
• m1u1 + m2u2 = m1v1 - m2v2
