Path of a Projectile – Rankers Physics

Ground to Ground Projectile: Practice Problem & Solution

Assertion (A): Path of a projected ball is parabolic in uniform gravitational field for oblique projection in absence of air resistance. Reason (R): Gravitational force is always act perpendicular to velocity during the motion of a projectile.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Ground to Ground Projectile. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is true because projectile motion under gravity without air resistance follows a parabolic path.

Reason (R) is false as gravitational force acts perpendicular to velocity only at the peak of the trajectory, not always. Thus, (A) is true, (R) is false.
