Unit 3: Investigating Forces & Motion

Front

Acceleration

Back

the rate at which an object changes its velocity

Front

Action force

Back

the force exerted by one object

Front

Applied force

Back

force that is applied on an object by a person or another object

Front

Balanced forces

Back

equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero

Front

Direct relationship

Back

when one variable increases, the other variable also increases

Front

Force

Back

a push or pull that can change the position or motion of an object / material

Front

Friction

Back

resists the motion of an object and always acts in the opposite direction of another object’s movement

Front

Gravity

Back

a force that pulls downward and can cause an object to change its motion

Front

Inverse relationship

Back

variables change in opposite directions: one increases while the other decreases, and vice versa

Front

Mass

Back

a measurement of the amount of matter in a sample
