Question

. Define velocity and acceleration in terms of time rate of change. Give their units too.​

Answer 1

Answer:

velocity = displacement/time dimensional formula is[LT–¹]. acceleration=velocity/time dimensional formula is [LT–²]

Answer 2

Answer :-

Velocity :-

It is defined as the rate of change of displacement covered by a body.

• It's SI unit is m/s.

• Velocity of a body can be in positive negative or zero.

• The slope of Displacement - Time graph gives velocity.

The formula for velocity is given by :- ★$\boxed{\sf{ v = \dfrac{s}{t}}}$

Acceleration :-

It is defined as the rate of change of velocity by a body is known as acceleration.

• It's SI unit is m/s².

• It can be in positive, negativity or zero.

• If velocity is uniform then the acceleration will be zero.

• The slope of velocity time graph gives acceleration.

The formula of acceleration is given by :- ★ $\boxed{\sf{a = \dfrac{v-u}{t}}}$
