Elastic Potential Energy¶
An object which can distort and return to its original shape, following Hooke's Law is known a spring - a common example being a coil spring.
When a string is stretched or compressed, it has elastic potential energy.
Equation¶
This equation will be on the Physics equation sheet!
\[
E_e = \frac{ke^2}{2}
\]
Where:
- \(E_e\) is the energy, in Joules (J)
- \(k\) is the spring constant, in newtons per metre (N/m)
- \(e\) is the extension, in metres (m)
