Solution

The correct option is B False
To get a uniform i.e. constant acceleration, slope of velocity-time graph has to remain same at all places on the graph. For that the graph has to be a straight line. The slope of a curve in velocity-time graph represents a non-uniform acceleration.

Above graph represents a uniform acceleration having a constant slope.

A object moves with uniform positive acceleration. Its velocity-time graph will be
(a) A straight line parallel to the time axis
(b) A straight line inclined at an obtuse angle to the time axis
(c) A straight line inclined at an acute angle to the time axis
(d) None of these.

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

(d) neither velocity nor acceleration is uniform.

For uniform motion :

(a) the distance-graph is a straight line parallel to the time axis.

(b) the speed-time graph is a straight line inclined to the time axis.

(d) the acceleration-time graph is a straight line parallel to the time axis.
