FAQs on Potential energy stored in a spring Video Lecture - Crash Course for PAT

1. What is work and energy?
Ans. Work is defined as the transfer of energy that occurs when a force is applied to an object and the object moves in the direction of the force. Energy, on the other hand, is the ability to do work or cause a change in an object.
2. How is work calculated?
Ans. Work is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. The formula for work is given as W = F * d, where W represents work, F represents force, and d represents distance.
3. What are the different types of energy?
Ans. There are several different types of energy, including kinetic energy (energy of motion), potential energy (energy stored in an object), thermal energy (heat energy), chemical energy (energy stored in the bonds of chemical compounds), and electrical energy (energy related to the movement of charged particles).
4. How is energy conserved in a system?
Ans. According to the law of conservation of energy, energy cannot be created or destroyed, but it can be transferred or transformed from one form to another. This means that the total energy in a closed system remains constant over time.
5. What is the relationship between work and power?
Ans. Power is the rate at which work is done or the amount of work done per unit of time. The relationship between work and power is given by the formula P = W/t, where P represents power, W represents work, and t represents time. This formula shows that power increases as the amount of work done in a given time period increases.
