Question
K in the elastic potential energy represents _______.
- Spring constant
- Spring count
- Spring mass
- Spring
Hint:
k is a measure of springs stiffness
The correct answer is: Spring constant
- The proportional constant k is called the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.
- Potential Energy =k ×(s×s)/2
