Force and Motion

Acceleration Change in speed and/or direction of an object’s motion.

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

Inertia Tendency of an object to resist change in motion.

Net Force Measurement of the total forces exerted on an object.

Speed Distance traveled by an object in a given amount of time.

Unbalanced Force Unequal forces on an object that may result in a change in position, direction or motion; net force does not equal zero.

Velocity A measurement of an object’s speed and direction.

Force A push or a pull that may cause a change in the motion of an object

Motion A change in an object’s position.

Potential Energy The energy an object has due to its position.

Kenetic Energy The energy an object has due to its change in position.

Work A push or a pull that changes the position of an object in the same direction as the push or pull.
