What is mass?
Force that acts on an object when it rubs against another object or material.

In order to change the motion of objects, you would have to apply this
What is an unbalanced/unequal force?
This is the force that acts on a space shuttle as it accelerates toward Earth.

What is Kinetic energy?
What is Gravitational Force/Gravity?
Name three contact forces that can cause an object to change motion. Be specific.

What is, it doesn't move?
Jackson was investigating the use of magnets to move objects. He observed that some objects moved toward the magnets without having to touch them. What type of force is that?
What is non-contact force?
List two non-contact forces that can cause objects to move.
What is gravity and magnetism?
Why does a ball change direction when a player kicks it from the side?
What is unbalanced forces?
This exists when all the forces acting on an object result in the object staying at rest or moving at a constant speed in the same direction.
