If the velocity time graph is some straight line parallel to the x axis, then definitely
The velocity and the acceleration are zero
The velocity and the acceleration are varying
Velocity is constant but the acceleration is varying.
Velocity is constant and the acceleration is zero.
Acceleration is zero which means that velocity is constant
The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is :
(a) velocity is uniform
(b) acceleration is uniform
(c) Both velocity and acceleration are uniform
(d) neither velocity nor acceleration is uniform.
Mark the correct statement(s) (1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.
(2) If velocity of a body is varying, its speed must be varying.
(3) A body moving with varying velocity may have constant speed.
(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.
