<h3><u>Explanation:</u></h3>
The term Motivation refers to a driving force that causes an individual to perform a specific task or show a behavior. Motivation can enhance an individual's performance at various levels.
Broadly, there are two types of motivation:-
<u>Intrinsic:</u> In this, the source of motivation is internal or within the individual's mind. These motivations are natural such as Hunger, Curiosity, Internal fear, Internal desire, etc.
<u>Extrinsic:</u> In this, the source of motivation is external. These motivations are not natural such as Rewards, Punishments, Incentives, etc.
