Question

What is acceleration

Answer 1

Acceleration means that change in velocity upon time taken for change......!

Answer 2

$<b>hey there..!!$

here is ur ans...

_______________________

✴ ACCELERATION :

In the previous example, the truck covered the distance AB at the velocity of 60 km/hour, BC at 30 km/hour and CD at 40 km/hour. It means that the velocity for the distance CD is greater than the velocity for the distance BC. From the number of seconds required for this change in velocity to take place, the change in velocity per second can be deduced. This is called Acceleration.

_______________________

✴ ACCELERATION

“The rate of change of velocity is called acceleration.”

OR

“Acceleration depends upon the velocity if the velocity continously increases or decreases the accelerattion will be produced."

1. Positive Acceleration

If the velocity continously increases then the acceleration will be positive.

2. Negative acceleration

If the velocity continously decreases then the acceleration will be negative.

_______________________

✴ FORMULA

Acceleration = change of velocity/Time
or a = (Vf-Vi)/t

✴ UNIT

The S.I unit of Velocity in M.K.S system is Meter/second+square
or m/S2
