Webb18 nov. 2024 · P.E is the potential energy of the object in Joules. m is the mass of the object in kg. g is the acceleration due to gravity in m/s². h is the height of the object with respect to the reference point in m. [ Put the values ] P.E = 10 × 10 × 5. P.E = 100 × 5. P.E = 500 joule ★ Therefore, The potential energy of a body is 500 J. WebbTo calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.
