Key Stage 3
Meaning
Hooke's Law states that the extension of an elastic object is proportional to the force applied to the object.
About Hooke's Law
- Hooke's Law describes how elastic objects behave when a pair of opposing forces is applied.
- Hooke's Law is described by the equation: Force = Spring Constant x Extension
 |
| When a weight is added the spring extends. If the weight is doubled the extension is also doubled. |
Equation
\( F = kx \)
\( F = k \times x \)
Where: \[F\] = Force applied \[k\] = Spring Constant (stiffness of the elastic object) \[x\] = Extension of the object
