How to use calculus in physics ?​

Explanation:

In Physics, many quanitties are the function of other quanitities.

For instance in kinematics, where the displacement (s), position (x), velocity (v) and time (t) are related.

Suppose the position can be descirbed as a function of time, i.e.

then since velocity is the rate of change of position, we write

which is the derivative of the poisiton/ time function.

On the other hand, the displacement of the particle is the sum of position changes over time, so the displacement can be defined by

which is the integration of postion/ time function.
