Choose Newton's Third Law of Motion. 

An unbalanced force is a force that causes a change in the motion of an object.

A Newton (N) is the same as force. 

Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Mass always represents the amount of matter in a particle or object and the unit of measurement is called a kilogram (kg). It is not the same as weight. 

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 is called.......

F=ma

A stationary bumper car is set in motion by the outside force of another bumper car colliding with it.

A rocket in outer space continues to move.

A magician pulls a table cloth from under a table of dishes.

A skater pushes another skater forward, but the one pushing moves backwards.

You push against a wall and the wall is pushing back on you.

As the fuel in a rocket ignites, the force of gas expansion and explosion pushes out the back of the rocket and pushes the rocket forward.

You are carrying a lunch tray when you bump into the edge of a table.  Although the tray did not tip, your milk falls off of the front of the tray.

Any push or pull on an object.

Which has more Inertia? (so need more force to move) 

Which type of force(s) will cause a change in an object's motion?

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

An automobile you are riding in suddenly stops, but you continue to go forward.

The action and reaction forces in any situation will always be...

What is mass usually measured in?

What is Newton's first law of motion?

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

An object at rest will remain at rest, and an object in motion will remain in motion unless
