Physics - Kinetic energy 0.0 / 5 PhysicsAstronomyGCSEAQA Created by: LunaShomeiRoseCreated on: 22-10-18 18:14 What is kinetic energy? Energy stored in moving object 1 of 11 How do you calculate it? 0.5 x mass x velocity(squared) 2 of 11 What are the units for Kinetic energy? Joules (J) 3 of 11 What is mass measured in? Kg 4 of 11 What is velocity measured in? m/s 5 of 11 A car runs on petrel, which is a store of ___ energy Chemical 6 of 11 Where does the chemical reaction take place? Engine 7 of 11 Chemical energy is converted to __ energy store as car moves Kinetic 8 of 11 The car has a mass of 700kg and speed of 20m/s. Calculate kinetic energy 0.5 x 700 x 20(squared) = 140,000J 9 of 11 We can convert answer to KJ (kilojoules). 1 KJ = 1000 J. Convert the answer. 140KJ 10 of 11 A ball is travelling 50m/s and has kinetic energy of 75J. Calculate mass of ball. 75/0.5 x 50(squared) = 0.06kg 11 of 11
