energy equation

• kinetic energy is movement, the equation is kinetic energy =

  0.5 multiplied by mass multiplied by velocity squared

  
• calculating the mass of kinetic energy

  mass is equal to kinetic energy divided by 0.5 multiplied by speed squared
• SPEED =

  kinetic energy = 0.5 multiplied by mass (square rooted)
• elastic potential energy =

  0.5 multiplied by spring constant multiplied by extension squared

  
• spring constant =

  elastic energy divided by 0.5 multiplied by extension squared

  
• extension =

  elastic potential energy divided by 0.5 multiplied by spring constant

  
• gravitational potential energy =

  mass multiplied by gravitational field strength multiplied by height

  
• gravitational field strength is measured in

  N/kg

  
• FORCE is in

  newtons
• work done =

  force multiplied by distance

  
• force =

  work divided by distance
• work is the energy used to move an object to certain distance
• distance =

  work divided by force
• resolution is the

  smallest measurement of an instrument
• power is the rate at which

  work is done
• power = energy transferred

  divided by time
• efficiency is equal to useful power

  output divided by total power input
• efficiency is a proportion of the input energy that is usefully
