physics equations i need to know paper 1 3.0 / 5 based on 1 rating ? PhysicsequationsGCSEAQA Created by: BL10Created on: 27-02-18 11:53 Weight= mass x gravitational field strength(g) 1 of 21 Work done= force x distance (along line of action of force) 2 of 21 Force applied by a spring= spring constant x extention 3 of 21 Kinetic energy= 0.5 x mass x (speed)*2 4 of 21 gravitational potential energy= mass x gravitational field strength(g) x height 5 of 21 Power= energy transferred/time 6 of 21 Power= work done/time 7 of 21 efficiency= useful output energy transfer/total input energy transfer 8 of 21 efficiency= useful power output/total power input 9 of 21 Charge flow= current x time 10 of 21 potential difference= current x resistance 11 of 21 power= potential difference x current 12 of 21 power= (current)*2 x resistance 13 of 21 energy transferred= power x time 14 of 21 energy transferred= charge flow x potential difference 15 of 21 density= mass/volume 16 of 21 KEY *2= squared /= divide x= multiply 17 of 21 elastic potential energy= 0.5 x spring constant x (extension)*2 18 of 21 change in thermal energy= mass x specific heat capacity x tempreture change 19 of 21 thermal energy for a change of state= mass x specific latent heat 20 of 21 (for gases) constant= pressure x volume 21 of 21
