Equations

• What is the equation that links gravitational field strength, mass and weight?

  Weight = Mass x Gravitational field strength

  W = mg
• What is the equation that links distance, force and work done?

  Work done = Force x Distance

  W = Fs
• What is the equation that links force, extension (or compression) and spring constant?

  Force = Spring constant x Extension (or compression)

  F = ke
• What is the equation that links force, moment and perpendicular distance?

  Moment = Force x Perpendicular distance

  M = Fd
• What is the equation that links area, force and pressure?

  Pressure = Force / Area

  P = F/A
• What is the equation that links distance, time and speed?

  Speed = Distance / Time

  s = d/t
• What is the equation that links displacement, time and velocity?

  Velocity = Displacement / Time

  v = s/t
• What is the equation that links acceleration, time and velocity?

  Acceleration = (Change in velocity) / time

  a = ∆v/t
• What is the equation that links acceleration, distance and velocity?

  2 x Acceleration x Distance = Final velocity^2 - Initial velocity^2

  2as = v^2 - u^2
