wikiHow Kinetic Energy Calculator Kinetic energy is the energy an object possesses by virtue of its motion. The kinetic energy of an object depends on its mass and velocity. To calculate the kinetic energy of an object, you can use the following formula: Kinetic energy (KE) = (1/2) x mass (m) x velocity (v)^2 where KE is the kinetic energy in joules (J), m is the mass in kilograms (kg), and v is the velocity in meters per second (m/s). Here are the steps to calculate the kinetic energy of an object: 1. Determine the mass of the object in kilograms. 2. Determine the velocity of the object in meters per second. 3. Square the velocity by multiplying it by itself. 4. Multiply the mass by the square of the velocity. 5. Divide the result by 2 to obtain the kinetic energy in joules. Here's an example to illustrate how this formula works: Let's say you have a ball with a mass of 0.5 kg and a velocity of 10 m/s. KE = (1/2) x 0.5 kg x (10 m/s)^2 KE = 0.25 x 100 KE = 25 J So the kinetic energy of the ball is 25 joules. Page
