Question

What is velocity... Explain with example

Answer 1

the velocity on an object is the rate of change of its position with respect to a frame reference and is a function of time.
For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an acceleration.

Answer 2

$\huge \leadsto \boxed{\pmb{ \bf{ \blue{Velocity}}}}$

• Velocity is the rate of change of position w.r.t time in a particular direction.

• Example :- Two cars moving with a speed of 40km/h , one towards the east and other towards the west. Then velocity of one car with respect to the other is negative.

• Displacement of a moving body per unit time is called the velocity of the body.

• Velocity = Displacement / Time taken

• Velocity is a vector quantity.

• It's SI unit is metre per second (m/s).

• Velocity can be negative.
