Investigating Force and Motion Unit 3

Front

Applied force

Back

A force that is applied to an object by a person or another object.

Front

Balanced forces

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

Friction

Back

The resistance that one surface or object encounters when moving over another.

Front

Gravity

Back

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

Front

Magnetism

Back

A force that can attract or repel objects that have a magnetic material like iron inside them.

Front

Net force

Back

The overall force acting on an object when all the individual forces acting on it are combined.

Front

Newton's Third Law of Motion

Back

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

Front

Normal force

Back

The support force exerted upon an object that is in contact with another stable object.

Front

Simultaneous force pairs

Back

Pairs of forces that occur at the same time, as described by Newton's Third Law.

Front

Unbalanced forces

Back

Forces that are not equal and opposite, causing a change in the motion of an object.
