Answer 1

The different types of velocities are uniform velocity, variable velocity, average velocity and ins tantaneous velocity.

Uniform velocity

A particle is said to be moving with uniform velocity if it covers equal displacements in equal intervals of time, that is, velocity remains constant throughout the motion. That is, when a body is moving with uniform velocity, the magnitude and direction of velocity remain the same at any point.

In this case, the displacement ‘s’ of the particle during a given time interval ‘t’ is obtained by taking the product of the velocity ‘v’ and the time interval ‘t’.

i.e., Displacement = velocity × time interval

or, s = vt

Variable velocity or non-uniform velocity

A body is said to be moving with variable velocity if its speed or direction or both change with time.

For example, consider a body circulating around a circle with uniform speed. Its velocity is variable as its direction changes with motion.
