The physical entities such as acceleration and height also contribute to the finding the velocity. Keep in mind that the integral of acceleration over time will yield velocity. m = Mass of object; KE = Kinetic Energy; v = Velocity of object; Kinetic Energy (KE) This is the kinetic energy of a moving object and represents the work done to accelerate it from rest, or decelerate it . Problem 6) some amount of force is exerted on an object to begin the motion; as the force of 87 N is applied, the body begins accelerated with the acceleration of 5 m/s2. vfinal2 = vinitial2 + [2 g ( s final - s initial)] The square of the final velocity equals the square of the initial velocity plus the product of twice the . .
