AIIMS 2018 Physics Projectile Motion MCQ Question
Assertion : If an object is projected from earth surface with escape velocity path of object will be parabola.
Reason : When object is projected with velocity less than escape velocity from horizontal surface and greater than orbital velocity path of object will be ellipse.
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 path of an object projected towards Earth follows a parabolic trajectory due to the influence of gravitational force, which acts as a constant downward acceleration (approximately 9.81 m/s²). This motion can be described by the equations of projectile motion, where the horizontal and vertical components of the object's velocity result in a curved path. Other options are not applicable in this context, as they do not pertain to the principles of projectile motion or the effects of gravity on the object's trajectory. Understanding this concept is crucial for analyzing motion in physics, particularly in scenarios involving gravity and initial velocity.
