Draw a velocity-time graph for the uniform motion of an object when the body is initially at rest.

Asked by AnalisaRhoades329

Answer (2)

When the body is at rest, its speed is zero, and the graph lies on the x-axis.
When the body is in uniform motion, the speed is constant, and the graph is a horizontal line, parallel to the x-axis and some distance above it.
It's impossible to tell, based on the given information, how these two parts of the graph are connected. There must be some sloping (accelerated) portion of the graph that joins the two sections, but it cannot be accounted for in either the statement that the body is at rest or that it is in uniform motion, since acceleration ... that is, any change of speed or direction ... is not 'uniform' motion'.

The velocity-time graph for an object initially at rest will start at the origin (0,0), indicating zero velocity. Once the object moves uniformly, it will show a horizontal line at a constant velocity (e.g., 5 m/s). This reflects the object's motion: resting initially and then moving at a constant speed.
