Velocity Formula Displacement/Time

Speed Formula Distance/Time
Newtons Laws of Inertia An object at rest stays at rest and an object in motion stay in motion, Unless acted on by an unbalanced force
Newtons Laws of Force and Acceleration The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Newtons Laws of Action-Reaction The size of the forces on the first object equals the size of the force on the second object.
Inertia a tendency to do nothing or to remain unchanged.
Newtons It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second
Mass a coherent, typically large body of matter with no definite shape.
Weight a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
Balanced Force Balance forces are two forces acting in opposite directions on an object, and equal in size.
Unbalanced Force Balance forces are two forces acting in opposite directions on an object, and equal in size.
Speed the rate at which someone or something is able to move or operate.
Velocity the speed of something in a given direction.
Acceleration increarse in the rate or speed of something
Friction the resistance that one surface or object encounters when moving over another.
Force strength or energy as an attribute of physical action or movement.
New Force In physics, something that causes a change in the motion of an object.
Motion the action or process of moving or being moved.
Dependent Variable/Independent Variable Dependent Variable depend on the Independent Variable. You can change the Independent Variable.
Constant occurring continuously over a period of time.
