constant acceleration

A straight downhill line on a velocity-time graph indicates __.

constant deceleration

Acceleration can be determined from the __ of a velocity-time graph.

gradient

__ states that an object will remain at rest or continue to travel with constant speed unless acted upon by an unbalanced force.

Newton's First Law

__ states that the acceleration of a body is proportional to the unbalanced force acting upon it and inversely proportional to the object's mass.

Newton's Second Law

__ states that if object A exerts a force on object B, then object B exerts an equal and opposite force on object A.
