Distance traveled= average speed x time (D= s x t) 1 of 18 SP1: How do you calculate acceleration? Acceleration= change in velocity- time taken ((A= (v-u)/t)) 2 of 18 SP2: What is the equation for calculating force? Force= mass x acceleration 3 of 18 SP2: How do you calculate weight? Weight= mass x gravitational field strength (W=m x g) 4 of 18 SP2: What is the calculation for momentum? Momentum= mass x velocity (P= m x v) 5 of 18 SP2: What is the equation for calculating work done? Work done= force x distance moved in the direction of force (E= f x d) 6 of 18 SP2: How do you calculate kinetic energy? 1/2 x mass x (speed)² (KE= 1/2 x m x v² ) 7 of 18 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 (ΔGPE= m x g Δh) 8 of 18 SP3: What is the equation for efficiency? Efficiency= (useful energy transferred by the device)/ (total energy supplied to the device) 9 of 18 SP4: How do you calculate the wave speed? Wave speed= frequency x wavelength (V= f x λ) OR wave speed= distance ÷ time (v= x/ t) 10 of 18 SP8: What is the calculation for power? Power= energy transferred/ time taken (W= J/ s) 11 of 18 SP9: How do you calculate the moment of a force? Moment of a force= force x distance normal to the direction of the force 12 of 18 How do you calculate energy transferred? Energy transferred= current x potential difference x time (E= I x V x t) 13 of 18 How do you calculate the amount of volts? Voltage= current x resistance (V= I x R) 14 of 18 How do you rearrange V= I x R to calculate the resistance? Resistance= voltage/ current (R= V/I) 15 of 18 How do you rearrange V= I x R to calculate the current? Current= voltage/ resistance (I= V/ R) 16 of 18 What is the equation for calculating density? Density= mass ÷ volume (P= m/ V) 17 of 18 How do you calculate the moment of a force? Moment of a force 18 of 18
