APR Quiz #2

What is the formula for calculating momentum?

• m=mv
• p=m/v
• p=v/m
• p=vm

The definition of momentum is

• The size of an object
• The velocity of an object
• Mass in Motion
• A comparison between two objects

The formula for momentum is

• mass divided by velocity
• mass multiplied by velocity
• velocity divided by mass
• Force times acceleration

What is Newton's First Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction

The formula for momentum is

• mass divided by velocity
• mass multiplied by velocity
• velocity divided by mass
• Force times acceleration

The momentum of an object depends upon the object's ___________&_____________.  

• size and shape
• mass and speed
• mass and velocity
• mass and energy

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

What can a force do?

• all of the above
• start a motion
• stop a motion
• change the direction of the motion

F=MA
