प्रश्न
Read the statement below carefully and state, with reason, if it is true or false:
The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point.
पर्याय
True
False
उत्तर
This statement is True.
Explanation:
At a point on a circular path, a particle appears to move tangentially to the path. Hence, the velocity vector of the particle is always along the tangent at a point.
