Equations

• What is the equation for mass?

  Weight = mass x gravitational field strength
• What is the equation for work done?

  Work done (energy) = force x distance moved
• What is the equation for power?

  Power = work done/time
• What is the equation for Gravitational Potential Energy?

  Gravitational Potential Energy = mass x gravity x height
• What is the equation for kinetic energy?

  Kinetic energy = 1/2 x mass x$Velocity^2$
• What is the equation for elastic potential energy?

  Elastic potential energy = 1/2 x spring constant x $extension^2$
• What is the calculation for the Hooke's Law?

  Force = spring constant x extension
• what is the equation for the distance travelled?

  Distance travelled = speed x time
• How can you calculate speed using distance travelled and time?

  Speed = distance/time
• What is the equation for acceleration?

  Change in velocity ( final velocity - initial velocity) /time taken
• How can you find the uniform acceleration?

  $\left(final\ velocity\right)^2\ -\ \left(initial\ velocity\right)^2\ =$$\ 2\ x\ accerlation\ x\ de\$
