Science Equations

• Kinetic energy


  1/2 x mass x speed²
• Elastic potential energy


  1/2 x spring constant x extension²
• gravitational potential energy


  mass x gravitational field strength x height
• Change in thermal energy


  mass x specific heat capacity x change in temp
• What is the formula for power in terms of energy transferred and time?

  Power = energy transferred / time
• power

  Energy transferred / time
• Power


  Work done / time
• efficiency
