Question

How do you define non-uniform acceleration ?

Answer 1

Non-uniform acceleration:

The acceleration of a body is said to be non-uniform if its velocity changes by unequal amounts in equal intervals of time .

Example :

1. Consider a body moving along a straight line,and let the velocity at a point O be 10$\frac{m}{s}$,when the stop watch is started ,the velocity of the body is found to be 12 $\frac{m}{s}$,15 $\frac{m}{s}$, 19$\frac{m}{s}$ and 26$\frac{m}{s}$,while at A,B,C,and D at time 1 ,2,3 and 4 seconds respectively .
2. It is clear that in each interval of 1s the velocity changes by different .
3. Such a body is said to be in non-uniform acceleration .
