What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation

The formula 
? = mass x acceleration
or 
? = m x a 
is used to find 

• Force
• Velocity
• Momentum
• Gravity

For every action, there is an equal and opposite reaction.

• Newton's
  1st
  Law of Motion
• Newton's
  2nd
  Law of Motion
• Newton's
  3rd
  Law of Motion

What is the attractive force that exists between all objects that have mass?

• Weight
• Mass 
• Gravity
• Viscosity

When a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?

• The cannon moving forward
• The cannonball moving forward
• The cannon moving backward
• The cannonball moving backward

Which is always a contact force?

• electric
• friction
• magnetic
• gravity

Newton's law of motion states that an object

• at rest remains at rest unless it experiences an unbalanced force.

• in motion maintains its velocity unless it experiences an unbalanced force.

• will tend to maintain its motion unless it experiences an unbalanced force.

• All of the above.

The first law of motion applies to

• only objects that are moving.

• only objects that are not moving.

• all objects, whether moving or not.

• no object, whether moving or not.
