Per NCERT, the INSTANTANEOUS VELOCITY at a point on a position-time graph is given by which geometric quantity?
AThe slope of the TANGENT to the x-t curve at that point
BTwice the slope of the secant
CThe area under the x-t curve
DHalf the distance from origin
Answer & Solution
Correct answer: A. The slope of the TANGENT to the x-t curve at that point
Per NCERT §2.2, instantaneous velocity = slope of tangent on x-t graph. The other options misstate.
