Assertion: A particle follows only a parabolic path if acceleration is constant.
Reason : In projectile motion path is parabolic, as acceleration is assumed to be constant at low heights.

Prove that the path of projectile is parabolic.

Assertion : A particle moves along circular path with constant speed then acceleration must be present. Reason : A particle moves with variable velocity then acceleration must be present.

A particle moves along the parabolic path y=ax^(2) in such a The accleration of the particle is:

Assertion: Projectile motion is uniformly accelerated motion. (Neglect the effect of air. ) Reason: In projectile motion, speed remains constant.

Assertion: Projectile motion is uniformly accelerated motion. (Neglect the effect of air. ) Reason: In projectile motion, speed remains constant.

Assertion: Projectile motion is uniformly accelerated motion. (Neglect the effect of air. ) Reason: In projectile motion, speed remains constant.

The question given below consist of an assertion and the reason . Use the following key to choose appropriate answer: Assertion: In projectile motion , path followed is a parabola because acceleration due to gravity near the surface of the earth remains constant . Reason , When acceleration of the particle is constant , then only possible path is parabola .

A spinning cricket ball does not follow parabolic path.

At the top of parabolic trajectory of projectile, the acceleration is
