Velocity-time graph of various types of motion of a body . When a body is moving with a constant velocity , the velocity-time graph is a straight line AB parallel to time axis. Velocity-time graph-1 The slope of velocity-time curve (representing the instantaneous acceleration) is zero. When a body is moving with a constant acceleration and its initial velocity is zero, the velocity-time curve is an oblique straight line , passing through origin. Velocity-time graph-2 Greater will be the slope of straight line OA, greater will be the instantaneous acceleration. When a body is moving with a constant acceleration and its initial velocity is not zero, the velocity-time curve is an oblique straight line AB not passing through origin. Velocity-time graph-3 A) Here OA represents the instant velocity of the boy. B) The area enclosed by the velocity-time figure with time axis ...
