Distance travelled= average speed x time 1 of 22 SP1: What's the equation for acceleration? Acceleration= change in velocity ÷ time 2 of 22 SP2: How do you calculate force? Force= mass x acceleration 3 of 22 SP2: What's the calculation for weight? Weight= mass x gravitational field strength 4 of 22 SP2: How do you calculate momentum? Momentum= mass x velocity 5 of 22 SP2: How do you find the work done? Work done= force x distance moved in the direction of the force 6 of 22 SP2: What's the equation for kinetic energy? Kinetic energy= 1/2 x mass x (speed)² 7 of 22 SP3: How do you calculate the change in gravitational potential energy? Change in gravitational potential energy= mass x gravitational field strength x change in vertical height 8 of 22 SP3: What's the calculation for efficiency? Efficiency= (useful energy tranferred by the device)/(total energy supplied to the device) 9 of 22 SP4: How do you calculate wave speed (1)? Wave speed= frequency x wavelength (λ) 10 of 22 SP4: How do you calculate wave speed (2)? Wave speed= distance ÷ time 11 of 22 SP8: How do you find power? Power= work done ÷ time taken 12 of 22 SP9: How do you calculate a moment of a force?
