Newton's Laws Test Review from Notes

Force and motion are related because:

• A force causes an object to move or change its motion.

• Motion always happens without any force.

• Force and motion are not related at all.

• Motion causes force to disappear.

Newton’s First Law of Motion states that:

• An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.

• Force equals mass times acceleration.

• For every action, there is an equal and opposite reaction.

• Energy cannot be created or destroyed.

What is force?

• A type of energy

• A push, pull, or twist upon an object

• A kind of motion

• A stationary object

What is inertia?

• The speed of an object

• An object's resistance to changing its motion

• The direction of an object

• The change in an object's velocity

What is velocity?

• The speed and direction of an object in motion

• The resistance to changing motion

• The change in an object's velocity

• The force acting on an object

Acceleration is the _____ in an object's velocity.

• change

• force

• distance

• direction

According to Isaac Newton, what happens when the forces on an object are unbalanced?

• The object will remain at rest

• The object will remain in constant motion

• The object will either speed up, slow down, or change direction

• The object will disappear
