The direction of the linear velocity of a body at a point moving along a circular path is:
Correct answer: A. Along the tangent
- A. Along the tangent
- B. Along the axis of rotation
- C. Directed away from the center
- D. Directed towards the center
Explanation
The linear velocity of a body moving along a circular path is directed along the tangent to the circle at the point where the body is located. This is because the velocity vector at any point on a circular path is perpendicular to the radius vector at that point. Therefore, the correct direction of the linear velocity is along the tangent to the circle at the given point.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
