Principles of Force Quiz

What is the basic definition of force?

• A measure of mass

• The speed of an object

• The distance an object travels

• A push or pull action on an object

According to Newton's First Law, what is required to change the motion of an object?

• A change in direction

• An external force

• A decrease in speed

• An increase in mass

How is acceleration related to force according to Newton's Second Law?

• Acceleration is inversely proportional to force

• Acceleration is directly proportional to force

• Acceleration is unrelated to force

• Acceleration is equal to force

What does Newton's Third Law of Motion state?

• An object in motion stays in motion

• Force equals mass times acceleration

• Acceleration is proportional to force

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

In the swimming example, what provides the swimmer with the height and distance needed?

• The water's resistance

• The swimmer's speed

• The reaction force from the blocks

• The swimmer's mass
