FAQs on Spring potential energy example (mistake in math) Video Lecture - Crash Course for PAT

1. What is spring potential energy?
Ans. Spring potential energy is the potential energy stored in a stretched or compressed spring. It is a form of elastic potential energy that arises from the deformation of the spring. When a spring is stretched or compressed, it gains potential energy that can be released to do work.
2. How is spring potential energy calculated?
Ans. The formula to calculate spring potential energy is given by: Potential Energy (PE) = (1/2) * k * x^2 where k is the spring constant (a measure of the stiffness of the spring) and x is the displacement from the equilibrium position of the spring.
3. Can spring potential energy be negative?
Ans. No, spring potential energy cannot be negative. The potential energy of a spring is always positive or zero. If the spring is stretched or compressed from its equilibrium position, it gains potential energy, which is positive. When the spring returns to its equilibrium position, the potential energy becomes zero.
4. What factors affect the spring potential energy?
Ans. The spring potential energy depends on two main factors: - The displacement (x): The greater the displacement of the spring from its equilibrium position, the more potential energy it will have. - The spring constant (k): A higher spring constant indicates a stiffer spring, which means it requires more force to stretch or compress it. Consequently, a higher spring constant will result in greater potential energy for the same displacement.
5. Can spring potential energy be converted into other forms of energy?
Ans. Yes, spring potential energy can be converted into other forms of energy. When a stretched or compressed spring is released, it converts its potential energy into kinetic energy as it oscillates back and forth. This conversion of energy allows the spring to perform work, such as moving objects or powering mechanical devices.
