Newton's Laws of Motion

Front

What explains a quantity that has BOTH speed and direction?

Back

Velocity

Front

What is the reason a ball bounces up when it hits the ground?

Back

The ball exerts a force on the ground, and the ground exerts a force on the ball.

Front

As more unbalanced force is applied to an object, its acceleration:

Back

increases

Front

What is Newton's First Law known as?

Back

The Law of Inertia

Front

What describes the backward motion of a boat when a person steps forward onto the dock?

Back

For every action there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is the formula for Newton's Second Law?

Back

F = ma (Force = mass x acceleration)

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked.

Front

What does friction do to the motion of an object?

Back

Friction opposes the motion of an object.
