level questions: Mechanical Energy Stores
| Question | Answer |
|---|---|
| What does a object gain at any given height. | It gains energy in its Gravitational Potential Energy Store |
| How can you work out Potential Energy? | Potential Energy [J]= Mass [kg] x Height [m] x Gravitational Field Strength [N/kg] |
| What does an object have when its moving? What can change the amount? | It has energy in its Kinetic Energy Store. It can change due to Mass or Velocity |
| What's the formula for Kinetic energy? | Kinetic Energy [J] = 0.5 x Mass [kg] x (Speed)² [m/s]² |
| What happens if you double the speed? | The energy in the Kinetic Energy Store quadruples due to it being squared in the formula. |
