Question

Define acceleration and write formula?

Answer 1

Answer:

It is the rate of change in velocity over time. Formula for Acceleration. Acceleration = Change in Velocity/Time Taken. Acceleration = (Final Velocity - Initial Velocity)/Time Taken. a = (v - u)/t

Answer 2

Answer:

The rate of change of velocity with respect to time.

The formula for acceleration is $a=\frac{\Delta v}{t}$

Explanation:

Acceleration is the rate at which the velocity of an item changes over time. Acceleration can occur as a result of a change in direction, a change in speed, or both.

The rate of change of velocity with respect to time.

$\text { acceleration }=\frac{(\text { final velocity })-(\text { initial velocity })}{\text { time }}$

$\text { acceleration }=\frac{\text { change in velocity }}{\text { time }}$

$a=\frac{v_{f}-v_{i}}{t}$

$a=\frac{\Delta v}{t}$

Where,

$a$ is the acceleration in $m.s^{-2}$

$v_{f}$ is the final velocity in $m.s^{-1}$

$v_{i}$ is the initial velocity in $m.s^{-1}$

$t$ is the time interval in $s$

$Δv$ is the small change in the velocity in $m.s^{-1}$
