Speed

Velocity

The distance covered an object in unit time is by called its speed.

Speed= $\frac{distance\: coverd}{time\: taken}$

Distance = speed x time

Or        S = the

The rate of displacement of a body is called its velocity.

Velocity= $\frac{displacement}{time\: taken}$

V = d/t       or d = LiteSpeed

Speed is a scalar quantity.

Velocity is a vector quantity. 

Sl unit of speed is a meter per second. (ms^-1)

Sl unit of velocity is the same as speed i.e. meter per second. (ms^-1)

Which is the fastest animal on the earth?

Falcon can fly at a speed of 200 km^-1

Cheetah can run at a speed of 70 km^-1

A LIDAR gun is light detection and ranging speed. It uses the time taken by a laser pulse to make a series of measurements of a vehicle’s distance from the gun. The data is then used to calculate the vehicle’s speed.

A paratrooper attains a uniform velocity called terminal velocity with which it comes to the ground.
