Question

What is the difference between average speed and instantaneous speed? What’s the difference between speed and velocity?

Answer 1

Explanation:

The average speed is the  displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.

In physics expressions

$Average speed=\frac{x_{2}-x_{1} }{t_{2}-t_{1} }$

Instantaneous speed=$lim_{t \to \infty} \frac{x}{t} =\frac{dx}{dt}$

b) Speed ​​denotes distance traveled divided by time, and instantaneous speed measures how quickly and in which direction does it move
