Force A push or pull on an object that may change the motion of the object.
Mass The amount of matter in an object.
Weight A measure of the force of gravity exerted on an object.
Net Force The overall force exerted on an object measure in Newtons.
Balanced Force Equal forces that do not cause a change in an objects motion.
Unbalance Force Unequal forces that cause a change in an objects motion-speed or direction.
Newtons The units used for forced.
Friction A force that resists motion when two surfaces are touching each other.
Gravity A force that pulls all objects that have mass toward one another.
Air Resistance The frictional force air exerts against a moving object.
Isaac Newton The scientist credited with the 3 laws of motion.
Motion Any change in the location of an object.
Newtons 1st Law An object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force.
Newtons The force of an object is equal to it's mass multiplied by it's acceleration.
Newtons 3rd Law For every action there is an equal and opposite reaction.
Inertia An objects tendency to resist a change in motion.
Speed The distance an object travels per unit of time.
Average Speed The total distance an object travels divided by the total time traveled.
Constant Speed Speed that remains the same or does not change.
Velocity Speed in a given direction.
Acceleration The rate of change of velocity which includes speeding up , slowing down, or changing direction.
Distance How far an object has traveled.
Displacement How far an object is away from where it started.
Work Using a force to move an object
