What is the definition of force?

• The change in speed over time.

• The newton, a metric unit of force.

• The acceleration of a falling object under the influence of Earth’s gravitational force.

• A push, pull, or action that has the ability to change motion.

What is Newton's first law of motion?

• An object at rest will stay at rest, and an object in motion will stay in motion.

• Acceleration is equal to the force acting upon it divided by its mass.

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

Even though every action force has an equal but opposite reaction force, they do not cancel each other out and motion may still occur because...

• The action and reaction forces are applied to the same object.

• The two forces have different magnitudes.

• The action and reaction forces are applied to different objects.

• The two forces have equal magnitudes.
