Forces and Motion Unit Review

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the unit of force?

Back

Newton (N)

Front

What happens to an object if the net force acting on it is zero?

Back

The object will remain at rest or move at a constant velocity.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, change direction, or change its state of motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of Newton's First Law in everyday life?

Back

Passengers lurching forward in a car when it suddenly stops.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause a change in motion.
