Which risen quantity is called force constant for unit displacement? What kind of energy is stored in the spring when it is stretched?
Understand the Problem
The question is asking which quantity is described as the force constant for unit displacement, likely in the context of springs or mechanical systems, and also inquiring about the type of energy stored in a spring when stretched.
Answer
Spring constant (k); Elastic potential energy.
The force constant for unit displacement is called the spring constant (k). The energy stored in the spring when stretched is elastic potential energy.
Answer for screen readers
The force constant for unit displacement is called the spring constant (k). The energy stored in the spring when stretched is elastic potential energy.
More Information
In Hooke's Law, the spring constant (k) quantifies stiffness and force needed for displacement. Elastic potential energy is stored in a spring when it is stretched or compressed, akin to potential energy stored due to gravitational effects.
Tips
A common mistake is to confuse elastic potential energy with kinetic energy. Remember, potential energy in a spring is stored in its position, not its motion.
