PHYSICS DEFINITIONS AND LAWS Grade 11 1. Average velocity is the rate of change of position. t d vave ? ? = ? ? 2. Average acceleration is the rate of change of velocity. t v aave ? ? = ? ? 3. Newton?s Laws of Motion: I. All objects at rest will stay at rest and all objects in motion will remain in uniform motion unless acted upon by an unbalanced force. II. If an unbalanced force acts on an object, then that object will accelerate in the direction of that force such that the acceleration is directly proportional to the force and inversely proportional to the mass of the object. m F a net ? ? = III. If object A exerts a force on object B, then object B will exert an equal force in the opposite direction on object A.
