Question

Define acceleration and write its s.i. unit and dimensional formula

Answer 1

Explanation:

In physics or physical science, acceleration (symbol: a) is defined as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² using an accelerometer.

dimensional formulae:

dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is. F = [M L T-2] It's because the unit of Force is Netwon or kg*m/s2.

pls mark me as brainliest

Answer 2

Answer:

acceleration defined as the rate of change of velocity with respect to time.

Explanation:

its si unit (m/s)^2

formula a=v-u/t

a = acceleration

v= final velocity

u= initial velocity

t= time
