Direct Relationship: correct answers When an increase of one variable results in an increase of
the other, or a decrease of one results in a decrease of the other.
Inverse Relationship: correct answers When one variable increases and the other one decreases,
or when one decreases and the other increases.

Acceleration: correct answers Chang in an object's velocity; occurs when an object:
*speeds up
*slows down &/or
*changes direction
Force: correct answers A push or pull exerted on an object.
Combined Forces: correct answers Two or more forces acting in the same direction on the same
object. They add to produce a net force that is stronger than any one of the forces.
Net Force: correct answers The sum of all forces acting on an object.
Opposing Forces: correct answers Two forces of the same magnitude acting on the same object
in opposite directions.
