Distance travelled = Average speed x Time 1 of 22 How do you calculate acceleration? Acceleration = (Final velocity - initial velocity) / Time 2 of 22 How do you calculate force? Force = Mass x Acceleration 3 of 22 How do you calculate weight? Weight = Mass x Gravitational field strength (10N/Kg) 4 of 22 How do you calculate energy efficiency? Engery efficiency = (Useful energy transferred by the device) / (Total energy supplied to the device) 5 of 22 How do you calculate Momentum? Momentum = Mass x Velocity 6 of 22 How do you calculate wave speed? (Including wavelength) Wave speed = frequency x wavelength 7 of 22 How do you calculate wave speed? (Including distance) Wave speed = distance / time 8 of 22 How do you calculate density? Density = Mass / Volume 9 of 22 How do you calculate work done? Work done = force x distance moved in direction of force 10 of 22 How do you calculate change in gravitational potential energy? Change in GPE = Mass x gravitational field strength x change in vertical height. 11 of 22 How do you calculate Kinetic energy? Kinetic energy = 1/2 x mass x (Velocity squared) 12 of 22 How do you calculate power? (Including work done) Power = work done / time 13 of 22 How do you calculate energy transferred? Energy transferred = charge moved x potential difference. 14 of 22 How do you calculate charge? Charge = current x time 15 of 22 How do you calculate Potential difference? Potential difference = current x resistance 16 of 22 How do you calculate Power? (Including energy transferred) Power = Energy transferred / Time 17 of 22 How do you calculate electrical power? (Including potential difference) Electrical power = current x potential difference 18 of 22 How do you calculate electrical power? (Including resistance) Electrical power = (Current squared) x resistance 19 of 22 How do you calculate force exerted on a spring? Force exerted on a spring = spring constant x extension 20 of 22 How do you calcuate the moment of a force? Moment = Force x distance 21 of 22 How do you calculate pressure? Pressure = Force normal to surface / Area of that surface 22 of 22
