strength or energy as an attribute of physical action or movement
Force
a tendency to do nothing or to remain unchanged
Inertia
the resistance that one surface or object encounters when moving over another.
Friction
the action or process of moving or being moved
Motion
slide uncontrollably on the wet surface of a road.
Hydroplaning
a point of time as measured in hours and minutes past midnight or noon.
Time
an instance of one moving object or person striking violently against another
Collision
a heavy object, especially one being lifted or carried
Weight
the force that attracts a body toward the center of the earth, or toward any other physical body having mass
Gravity
a coherent, typically large body of matter with no definite shape
Mass
the quantity of motion of a moving body, measured as a product of its mass and velocity
Momentum
frictional force air exerts against a moving object.
Air resistance
two forces acting in opposite directions on an object, and equal in size.
Balanced forces
Forces that cause a change in the motion of an object
Unbalanced forces
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
Terminal velocity
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newtons 1st law
a vehicle's capacity to gain speed within a short time
Acceleration
he rate at which someone or something is able to move or operate
Speed
the moving of something from its place or position
Displacement
friction that exists between a stationary object and the surface on which it's resting.
Static friction
