Deforming forces and restoring force
Stress, strain and Hooke's law · Physics
Study notes
A metal spring has a length of 10 cm. When a 5 Newton force is applied, it stretches to 12 cm. 1. Identify the deforming force: The 5 N force is the deforming force. 2. Calculate the change in length (extension): 12 cm - 10 cm = 2 cm. 3. Identify the restoring force: The spring exerts an equal and opposite force of 5 N to return to 10 cm. 4. Conclusion: The deforming force caused a 2 cm extension, and the restoring force is 5 N in the opposite direction.
