What is Newton's first law of motion?

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

• Force is mass times acceleration

• An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force.

What unit do we use to measure force?

• Newtons

• Joules

• Inches

• Meters

What does Newton's second law of motion state?

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

• Force is mass times acceleration.

• An object at rest will stay at rest and an object in motion will stay in motion, unless acted on by an unbalanced force.

How do we calculate the net force acting on an object?

• You multiply the two forces acting on the object.

• You divide the two force acting on the object

• You add the two forces acting on the object

• You subtract the bigger force from the smaller force that is acting on the object.
