Kinetic Energy Practice Problems
msbclasses.weebly.comKinetic Energy Practice Problems 1. What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s? KE = ½ mv2 KE = ? m = 150kg v = 15m/s KE = ½ (150kg) (15 m/s)2 KE = ½ (150kg)(225) KE = 16875J 2. An object has a kinetic energy of 25 J and a mass of 34 kg , how fast is the object moving? KE = ½ mv2 KE = 25J m = 34kg v = ?

AP Physics 1- Work, Energy, & Power Practice Problems ...
www.pedersenscience.comAP Physics 1- Work, Energy, & Power Practice Problems ANSWERS FACT: The amount of work done by a steady force is the amount of force multiplied by the distance an object moves parallel to that force: W = F x cos (θ). The units are N. m, which equal a Joule (J). Positive work is done by a force parallel to an object’s displacement.

www.uek12.orgthe energy is transformed from the potential energy (stored energy) to the energy of movement (kinetic energy). The more you pull back on the car, the farther it will travel forward. Because no system is perfect, one-hundred percent of the potential energy is not converted to kinetic energy. Some of the energy is lost to heat and sound.
