Physics equations

• Work done = force x distance moved
• Moment = force x perpendicular distance from the pivot
• efficiency = useful (power/energy) output / total (power/energy) input
• Power = energy transfered / time taken to transfer it
• Kinetic energy = 1/2 x mass x velocity ^2
• Gravitational potential energy = mass x gravitational field strength x height
• Force = spring constant x extension
• Weight = mass x gravitational field strength
• Acceleration = change in velocity/ time taken
• Density = mass / volume
• Speed = distance /time taken
• Pressure = force / area
• What is the equation for Momentum?

  P = M x V
• What is the equation for velocity?

  Velocity = displacement / time
• What is the equation for charge flow ?

  Charge flow = current x time
• Force = acceleration x mass
