The motion of a particle is given by a straight line in the graph given above drawn with displacement (x) and time (t). Which one among the following statements is correct ?

Options

A. The velocity of the particle is uniform
B. The velocity of the particle is non-uniform
C. The speed is uniform and the particle is moving on a circular path
D. The speed is non-uniform and the particle is moving on a straight line path

Answer

A

Explanation

Slope is constant, and the slope of x, t graph gives velocity, so velocity is constant i.e. uniform.
