Hello students, in this video first we will discuss about energy.
00:08
Energy is a fundamental concept in physics and refers to the ability of a substance to do work or cause change.
00:34
It is a scalar quantity that can be measured in june's represented by j.

Now let's discuss about kinetic energy and potential energy.
01:01
Kinetic energy refers to the energy of motion.
01:11
An object that is moving has kinetic energy.
01:16
The amount of kinetic energy that it has is proportional to its mass and the square of its velocity.
01:40
Whereas potential energy refers to the stored energy that has the potential to be converted into kinetic energy, an object that is at rest but has the potential to move has the potential energy.
02:12
Example of potential energy includes chemical energy stored in molecules.
02:28
Gravitational potential energy and elastic potential energy.
02:37
Now let's look at free energy and activation energy.
02:41
Free energy refers to the amount of energy available to do work in a system...
