Newton's Laws of Motion

The tendency of an object to remain at rest or in motion unless it is acted on by a force.

• Newton's 1st Law

• Newton's 3rd Law

• Inertia

• Both A and C

What is a push or pull that can make an object speed up, slow down, or change direction

• force

• friction

• energy

• gravity

If you see an object changes its motion, what has happened to it?

• an unbalanced force acted on it

• a balanced force has acted on it

• friction has been applied to it

• inertia is acting against it

An object has a 60N force pulling to the left and a 70 N force pulling in the opposite direction. What is the net force acting on the object?

• 10 N to the right

• 10 N to the left

• 60 N to the left

• 70 N to the right

Which force always pulls downward on objects?

• energy

• friction

• gravity

• air resistance

Which one of the following objects has the greatest inertia?

• ping pong ball

• golf ball

• soft ball

• bowling ball

Describe the motion of a person not wearing a seat belt if the car stops suddenly.

• The car will stop and the person will keep moving forward because of inertia.

• The car will stop and the person will speed up.

• The person will stop faster than the car because they are lighter.

• The person and car will stop together.

Which of Newton's Laws is responsible for what occurs in the prior question?

• Newton's Mother-in-Law

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

When you walk across the ground and push on it with your feet... what happens?

• The ground pushes back less strongly than your feet.

• There is no effect on the ground.

• The ground pushes back on your feet with equal force.

• The ground pushes back more strongly than your feet
