Question
In the spring and block system, the force which brings the block back to its equilibrium position is __________ force.
- Gravity
- Elastic force
- Tension force
- Frictional force
Hint:
Elasticity is the ability of a material to return to its original shape after being stretched or compressed.
The correct answer is: Elastic force
Elasticity is the ability of a material to return to its original shape after being stretched or compressed. This property is called elasticity. As you stretch or compress an elastic material, it resists the change in shape. This force is called elastic force.
