Newton's Laws of Motion

Because of inertia, a resting object ________.

• will remain at rest

• will move at a constant speed

• will eventually move

• is unbalanced

The first law of motion states that objects in motion will:

• stop

• accelerate

• stay in motion

• rest

The first law of motion states that objects at rest will stay at rest unless acted upon by an unbalanced:

• motion

• force

• inertia

• acceleration

Newton's second law of motion states that an unbalanced force is equal to mass times:

• acceleration

• force

• motion

• inertia

What is the formula for the 2nd law of motion?

• a=lw

• F=m/a

• F=ma

A skateboarder pushes the ground BACKWARDS which causes the board to move FORWARD.

• Newton's 1st Law of Motion

• Newton's 2nd Law of Motion

• Newton's 3rd Law of Motion

It is much more difficult to move a dresser full of clothes than an empty dresser.

• Newton's 1st Law of Motion

• Newton's 2nd Law of Motion

• Newton's 3rd Law of Motion

An object in motion stays in motion and an object at rest stays at rest UNLESS

• acted on by a balanced force.

• acted on by an unbalanced force.

When a horse stops suddenly, the rider on its back continues to move forward onto the ground. Which law is this?
