Energy and Its Transformation
What is Energy ?
Energy is a very common word frequently used in our day-to-day life. The universe is made up of matter and energy. In physics, energy is the ability to do work, or the ability to move or elicit change in matter.
In other words, energy measures the capability of an object or system to do work on another object or system.
We require energy for all types of activities including the activities within our body, with our body, or with other bodies. When we say a body has energy, it means it is capable of doing doing work.
Various types of Energy are :-
When a body comes down from a height its potential energy decreases where as its kinetic energy increases.
The kinetic energy of a moving body depends on
Energy Transformation is defined as the process of changing energy from one form to another.
During transformation of energy from one form to another it remains constant. This is known as Law of Conservation of Energy.
