 Acceleration The change in Velocity divided by the time interval Constant A quantity that does not change in an equation ex; g = 9.8m/s.s is the constant of gravity due to free fall. elliptical moving in a round path. ex; the planets move in an elliptical orbit energy non material property of causing changes in matter force Agent that results in accelerating or deforming an object. free fall the falling of an object without any disturbance apart from earths gravity. friction a force that opposes motion frictionless without opposition of motion impulse product of force and the time interval at which it occurs Independent Variable A variable that is manipulated or change during an experiment.

Kinetic relating to motion Kinetic Energy Energy possessed by an object because of its motion. Law of Conservation of A statement that states that a certain quantity after a certain occurance does not change. Momentum The product of the mass and velocity of a moving body. Magnitude The size of something Mass A measure of the quantity of matter; a fundamental physical quantity. Momenta The Plural of momentum the products of its masses and velocities. net force Vector sum of forces on an object. Net Impulse Vector sum of impulses on an object Newtons The unit of force; a derived unit having the dimensions kg m/s2. Potential relating to not in motion like kinetic energy which is energy of an object at rest Power The time rate of doing work. power factor. The cosine of the phase angle between current and voltage in an a-c circuit. Radius A line segment that joins the center of a circle with any point on its circumference. Scientific notation A positive number expressed in the form of M x 10n in which M is a number between 1 and 10 and n is an integral power of 10. Speed limit The highest or lowest speed you can move at. static Having no motion; being at rest; quiescent. vector A quantity that is completely specified by a magnitude and a direction. Velocity Speed in a particular direction. Volume The density of and object divided by its mass Weight The measure of the gravitational force acting on a substance. work The product of a displacement and the force in the direction of the displacement. y-intercept The Vertical axis of any graph.
