Which quantity does kinetic energy NOT depend on? What is the unit of energy? A cyclist doubles her speed. What happens to her kinetic energy? Which formula gives gravitational potential energy? A 2.0 kg bag is lifted 3.0 m. What is its GPE (g = 9.8 N/kg)? A ball falls from a shelf. Which change happens? What is the kinetic energy of a 0.20 kg ball at 5.0 m/s? Where does a swinging pendulum have its greatest kinetic energy? A sled slides down a hill and ends with less KE than the GPE it started with. Where did the rest go? Object X has twice the mass of object Y and both have the same speed. How do their kinetic energies compare? Define kinetic energy. — Energy an object has because it is moving. Formula for kinetic energy? — KE = ½ × m × v² Define gravitational potential energy. — Energy stored because of height above the ground. Formula for gravitational potential energy? — GPE = m × g × h What is the SI unit of energy? — The joule (J) Value of g used on Earth? — 9.8 N/kg Speed doubles. What happens to KE? — It becomes four times larger. Mass doubles at the same speed. KE? — It doubles. What happens to GPE when an object falls? — It decreases as it becomes kinetic energy. Where does energy go when friction acts? — To the surroundings as thermal energy. Keep going with Lina
