concept of potential energy definition
Answers
♨ What is potential energy?!
↪ The energy possessed by a body due to its change in position or shape is termed as potential energy.
♨ What are it types?!
☞ Gravitational potential energy:-
A lifted weight can do work when it falls down
For instance, water stored in reservoirs- It is the potential energy of the water that generates electricity.
☞ Potential energy due to configuration:-
[Change in shape]
↪A coiled spring in watch, clocks, toys.
↪Stretched bow:- When the bow is released, it is able to shoot the arrow with a large velocity.
↪ Compressed gas in cylinders.
♨ Potential energy of an object at a height:-
Consider an object of mass, m. Let it be raised at a through a height, h. Let the work done on the object against gravity be W. i.e,
W = f × s
= mg × h
= mgh.
Therefore, Ep = mgh.
