Force and Motion Review

What is speed?

• distance traveled divided by time traveled

• distance traveled divided by time traveled with direction

• distance traveled multiplied by time traveled with direction

• distance traveled multiplied by time traveled

What is velocity?

• distance traveled divided by time traveled

• distance traveled divided by time traveled with direction

• distance traveled multiplied by time traveled with direction

• distance traveled multiplied by time traveled

What is acceleration?

• distance traveled divided by time traveled

• distance traveled divided by time traveled with direction

• change in velocity divided by time

What is meant by "unbalanced force"?

• an object at rest or moving at a constant speed

• an object speeding up, slowing down, or changing direction

What is meant by "balanced force"?

• an object at rest or moving at constant speed

• an object speeding up, slowing down, or changing direction

How is force calculated when different amounts of force are applied to an object in opposite directions?

• add

• subtract

• multiply

• divide

How is force calculated when different amounts of force are applied to an object in the same direction?

• add

• subtract

• multiply

• divide

What are Newton’s three laws of motion?

• Law of Inertia

• Law of Force and Acceleration

• Law of Action-Reaction

• All of the above

What is the law of inertia?

• The tendency of an object to resist a change in motion.

• Force = mass x acceleration

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