NEET Physics (general) MCQ Question
Consider a diagram showing the path of an object with velocity vectors at points P, P1, P2, and P3, where P represents the position of the object at time t, and P1, P2, P3 represent positions after time intervals Δt1, Δt2, Δt3 respectively, with Δt1 > Δt2 > Δt3. Which statement about the instantaneous acceleration of the object at point P is correct?
Instantaneous acceleration is the limiting value of average acceleration as the time interval approaches zero.
Instantaneous acceleration points in the direction of the velocity vector at point P.
Instantaneous acceleration is always perpendicular to the path of the object.
Instantaneous acceleration is independent of the time intervals Δt1, Δt2, and Δt3.
Correct Answer
Detailed Explanation
Instantaneous acceleration is defined as the limiting value of the average acceleration as the time interval approaches zero, as described in the NCERT context.
