Unformatted text preview: becomes equal to the instantaneous acceleration a. Acceleration is the rate at which the velocity is changing. When an object moves with a constant acceleration along a straight line, its displacement x  x , final velocity v , initial velocity v , acceleration a , and the elapsed time t are related by the following equations, assuming that x = 0 m at t = 0 s: These equations can be combined algebraically to give two additional equations. See Table 2.1 . The equations in this table are known as the equations of kinematics. In freefall motion, an object experiences negligible air resistance and a constant acceleration due to gravity. All objects at the same location above the earth have the same acceleration due to gravity. The acceleration due to gravity is directed toward the center of the earth and has a magnitude of approximately 9.80 m/s 2 near the earth's surface....
