Download potential and kinetic energy calculations worksheet and more Exams Physics in PDF only on Docsity! Name: ___________________________ POTENTIAL AND KINETIC ENERGY CALCULATIONS WORKSHEET In Lesson 15.1, you learned that Potential Energy = mass x gravity x height. The formula can also be written to find mass or height. Use the below formulas to solve the following problems. Potential Energy = mass x gravity x height Units: J Mass = Potential Energy / (gravity x height) Units: kg Height = Potential Energy / (mass x gravity) Units: m Gravitational Constant = 9.8 m/s​2 In Lesson 15.1, you learned that Kinetic Energy = ½ x mass x velocity​2​. Kinetic Energy = ½ x mass x velocity​2 Units: J 1. Calculate the potential energy of a rock with a mass of 5 kg while sitting on a cliff that is 30 m high. 2. Calculate the potential energy of an object with a mass of 15 kg while sitting on a shelf that is 20 m high. 3. Calculate the potential energy of a statue with a mass of 20 kg while sitting on a table that is 2 m high. 4. What distance is a book from the floor if the book contains 195 Joules of potential energy and has a mass of 5 kg? 5.
