Question

If a body starts from rest and moves with uniform acceleration, then the displacement of the body is directly proportional to the cube of the time.

• A. True
• B. False

Answer 1

The correct option is B False

Initial velocity of the body $u=0$

Let the constant acceleration be $a$.

Displacement of the body $S=ut+\frac{1}{2}a{t}^2$

$\therefore$ $S=0+\frac{1}{2}a{t}^2$

We get $S=\frac{a{t}^2}{2}$

Thus, displacement of the body is directly proportional to the square of the time.
