❓ Frequently Asked Questions 🎙️
❓ What is Hooke Law?
Hooke Law states that the restoring force of an elastic object is directly proportional to its displacement, provided the elastic limit is not exceeded.
❓ What is the formula of Hooke Law?
The mathematical expression is:
F = −kx, where
• F = restoring force
• k = spring constant
• x = extension or compression
❓ What does the spring constant represent?
The spring constant (k) indicates the stiffness of a spring. A higher value means a stiffer spring.
❓ Is Hooke Law valid for all materials?
No. Hooke’s Law applies only within the elastic limit of a material.
