Question

Differentiate between Uniform acceleration and variable acceleration.

ICSE Class 9 Physics Chapter Motion in One Dimension

Answer 1

Uniform Acceleration
(i) In uniform acceleration, equal changes in velocity takes place in equal intervals of time
Variable Acceleration
(i) In variable acceleration, changes in velocity are not equal in equal intervals of time
Uniform Acceleration
(ii) Free fall of an object is an example of uniform acceleration
Variable Acceleration
(ii)Motion of a vehicle on road is an example of variable acceleration

Answer 2

Explanation:

Uniform acceleration:

if the rate of change of velocity changes equal in equal intervals of time it is said to be uniform acceleration ..

Variable acceleration:

if the rate of change of velocity changes unequally in equal intervals of time it is said to be variable acceleration..
