PHYSICS Energy forces and energy 0.0 / 5 PhysicsForcesGCSEAQA Created by: [email protected]Created on: 16-05-18 17:25 What is work done and energy transferred measured in? Joules, J 1 of 8 What is the equation for work done? W=F(force applied, N) X D(distance, M) 2 of 8 What is power? A measure of how quickly work is being done and so how quickly energy is being transferred. 3 of 8 What is the equation for power? P(measured in W, watts)=E(work done/energy transferred,J) % T(time, S) 4 of 8 What two things changes the amount of gravitational potential energy on an object? Mass and height above ground. 5 of 8 What is the equation for the change in gravitational potential energy? Ep(J)=M(mass,KG) X G(gravitational field strength,N/KG) X H(change in height, M) 6 of 8 What two things does kinetic energy depend on? Mass and Speed. 7 of 8 What is the equation for kinetic energy? Ek(kinetic energy, J)=0.5 X M( mass, KG) X V²(Speed, M/S) 8 of 8
