AIIMS 2019 Physics Projectile Motion Assertion Reason Question
Assertion: When a body is dropped or thrown upward from the same height, it would reach the ground at the same time. Reason: Direction of projection does not affect the time of flight.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is false because a body thrown upward will take longer to return to the ground compared to a body dropped from the same height, due to the additional time spent ascending before descending. The reason is also false; the direction of projection does affect the time of flight, as the initial velocity and the influence of gravity play crucial roles in determining the trajectory and duration of the motion. Options A and B are incorrect because they assume both statements are true, while option C incorrectly claims the assertion is true. Understanding these concepts is essential in kinematics, where the effects of initial velocity and gravitational acceleration are fundamental to analyzing motion.
