| Question | Answer |
| A Force acting on an object may cause it to... | ... change shape. |
| An elastic object, E.G a spring, stores... | ... elastic potential energy when stretched or squashed. |
| When spring is stretched, what is happens? | Work done in stretching, it is stored as elastic potential energy. |
| When the force is removed, the elastic potential energy... | ... causes it to return to its orginal shape. |
| The extension of an elastic object is... | ... directly proportional to the force applied. |
| The proportionality is true until the elastic limit is reached, after that... | ... the object is completly deformed. |
| The Formula is Know as Hooke's Law... | F = K x e F is the force in newtons (N) k is the 'spring constant' in newtons per metre, (N/m) e is the extension in metres, (m) |
| Different materials have... | ... different spring constants. |
| An example of Hooke's Law: |
