Kinetic energy 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: nimrahali12Created on: 30-10-16 10:50 What is kinetic energy? the energy of movement 1 of 17 What is the formula? Kinetic energy(joules)=1/2 times mass (kg) times speed2 (m/s) 2 of 17 The more it weighs and faster? the bigger kinetic energy 3 of 17 Kinetic energy transferred is? work done 4 of 17 Conservation of energy states that energy can never be? created or destroyed-only converted into different forms 5 of 17 A moving car has lots of kinetci energy-to slow a car down this kinetic energy needs to be converted into? other types of energy 6 of 17 To stop a car , the kinetic energy (1/2mv2) has to be converted into? heat energy as friction between the wheels and the brake pads causing the temps of the brakes to incrase 7 of 17 What is the formula for kinetic energy transferred? Kinetic energy transferred (1/2mv2)=work done by brakes (f times d) 8 of 17 What is the formula? 1/2mv2 (mass of cars and passengers in kg) (speed of car in m/s)=f (maxium braking force in N) times d (braking distance in m) 9 of 17 Falling objects convert ep to? ek 10 of 17 What happens when something falls? Its potential energy is converted into kinetic energy 11 of 17 What is the formula? kinetic energy gained=potential energy lost 12 of 17 Some ek is transfererd into? heat and sound 13 of 17 When meteors and space shuttles enter the atmosphere , they have? a very high kinetic energy 14 of 17 Friction due to collision with particles in the atmosphere transfers some of their? kinetic energy to heat energy and work is done 15 of 17 The temps can become so extreme that most meteors make it through to earths surface called? meteorites 16 of 17 Space shuttles have? heat sheilds made from special materials which lose heat quickly allowing the shuttle to re enter the atmosphere without burning up 17 of 17
