Question

What are the types of Velocity?​

Answer 1

Explanation:

The Types of Velocity

• Constant Velocity. An object with a constant velocity does not change in speed or direction. ...
• Changing Velocity. Objects with changing velocity exhibit a change in speed or direction over a period of time. ...
• Mathematics of Acceleration. ...
• Instant Velocity. ...
• Terminal Velocity.

Answer 2

Velocity-

Net displacement of a particle in per unit time is known as velocity.

Important Points-

=> Velocity is a vector quantity and its unit is metre per second.

=> For moving body velocity may be +ve, -ve or 0.

=> Direction of average velocity is always along the net displacement means from initial to final position but the direction of instantaneous velocity is always tangential to the path [See the attachment where (i) and (ii) show Instantaneous Velocity ].

Types of Velocity-

1. Uniform Velocity -

If magnitude and direction of velocity remain unchanged then it is known as uniform velocity.

2. Non-uniform Velocity -

If either of magnitude or direction change then it is known as non uniform velocity.

Some Important terms and formula's-

1. Average velocity-

The ratio of total displacement and total time taken by the particle is known as average velocity.

$Vavg \: = \frac{total \: displacement}{total \: time \: taken}$

2. Instantaneous velocity -

The velocity of a particle at a particular instant or movement is known as instantaneous velocity.If time interval is made infinitely or negligible small then average velocity is converted into instantaneous velocity.

$Vinstantaneous \: = \: \frac{dr}{dt}$
