Question

For an object in uniform circular motion, what is the direction of its acceleration?

Options

Choose one · Correct answer highlighted

Tangential to the path Correct Towards the center of the circle Away from the center Along the velocity vector

Explanation

Velocity v=v₀+at. Starting from rest, v=at. With a=(ax i+ay j), magnitude |v|=t√(ax²+ay²) per NCERT vector addition. Substituting ax, ay, t gives |v| equal to Tangential to the path. Hence option A is correct.
