Question

Assertion: Circular and projectile motions both are two dimensional motion. But in circular motion, we cannot apply v = u + at directly, whereas in projectile motion we can. Reason: Projectile motion takes place under gravity, while in circular motion gravity has no role.

TestHub · Accepted Answer

The Assertion is true: in circular motion $a$ is not constant, so $v = u + a t$ cannot be applied directly, while in projectile motion $a = g$ (constant) allows it.
The Reason is false: in vertical circular motion gravity plays an important role.
