Question
What is the difference between velocity-time graphs in uniform motion and uniformly accelerated motion?
✓
Answer
The motion of a body moving with constant velocity is called uniform motion. In uniform motion a line is obtained between the graph of velocity (v) and time (t) parallel to time. In uniformly accelerated motion, the instantaneous acceleration of a body at a point is equal to the slope of the tangent line drawn on the velocity- time graph at that instant.
According to graph, the velocity of the object will increase with time. The value of its slope (a) can be determined $a=\tan \theta$.
