Equations Flashcards
Equation for distance
Distance Travelled = average speed x time
Equation for acceleration
Acceleration = (v^2 - u^2) / t
Equation for force
Force = mass x acceleration
Equation for efficiency
Efficiency = useful energy / total energy
Equation for momentum
Momentum = mass x velocity
Equation for wave speed
Wave speed = frequency x wavelength
Equation for work done
Work done = force x distance moved in that direction
Equation for change in gravitational potential energy
Mass x gravitational field strength x change in vertical height
Equation for Kinetic energy
0.5 x mass x velocity^2
State the four Equations for power
Power = energy transferred / time
Equation for Weight
Weight = mass x gravitational field strength
Equation to calculate a moment
Moment = force x distance from pivot
Equation for pressure
Pressure = force / surface area
State the equation for wave speed
Wave speed = frequency x wavelength
Equation for energy transferred (electricity)
Energy = charge x potential difference
