Unit 10 Test Review: Force and Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What is mass?

Back

The amount of matter in an object, which does not change regardless of location in the universe.

Front

What is weight?

Back

The force exerted by gravity on an object, which can change depending on the object's location.

Front

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

Back

According to Newton's Second Law, force equals mass times acceleration (F = ma).

Front

What does a constant speed graph look like?

Back

A straight, diagonal line on a distance-time graph.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car, causing it to move.

Front

What is inertia?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
