Trajectory with Constant Acceleration – Rankers Physics

Ground to Ground Projectile: Practice Problem & Solution

Assertion (A): Trajectory of an object moving under a constant acceleration is a straight line. Reason (R): The shape of trajectory depends only on the acceleration.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution Explained:

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:

An object under constant acceleration does not always follow a straight line (e.g., projectile motion is parabolic). A straight line occurs only if initial velocity is parallel or anti-parallel to acceleration. So (A) is false. The trajectory shape depends on both initial velocity and acceleration. So (R) is false.

1. Assertion (A): In any interval, the magnitude of displacement is always less than or equal to the distance travelled. Reason (R): For a particle travelling in a straight line with constant acceleration, the magnitude of the change in the velocity during any interval is always less than or equal to the change in the speed during that interval.  
2. Assertion (A): When the range of a projectile is maximum, the time of flight is the largest. Reason (R): Horizontal range is maximum when angle of projection is (90^circ).
