Elastic Potential Energy Calculations | GCSE Physics
Elastic potential energy is stored in squashed or stretched objects like springs.
Why is extension squared in the energy formula?
What is Elastic Potential Energy Calculations | GCSE Physics?
"Energy stored in an elastic object when it is deformed by a force."
Which law states that energy cannot be created or destroyed?
Why can efficiency never be 100% in a mechanical system?
A 5 kg weight is lifted 2 metres. Calculate its GPE (g = 9.8).
Which formula is used to calculate kinetic energy?
Spring Energy
Energy is stored when an object is deformed elastically.
The formula is Ee = 1/2 k e².
k is the spring constant (N/m), e is the extension (m).
This energy is recovered when the object returns to its original shape.
Square check: Just like kinetic energy, the extension (e) must be squared BEFORE multiplying by 0.5 and k.
