Question

Figure shows velocity-time graph for various situations. What does each graph indicate?

✓

Answer

Initial velocity, u > 0. Also, velocity is constant with time. Hence, acceleration is zero.
As finite initial velocity is increasing with time, acceleration, a > 0 and is constant.
Initial velocity, u = 0. Velocity is increasing with time so, acceleration a is positive. But it is decreasing in magnitude with time.
Initial velocity, u = 0. Velocity is linearly increasing with time. Hence, starting from rest acceleration is constant.
Initial velocity, u = 0. Acceleration and velocity is increasing with time.
Initial velocity u > 0. Velocity decreases and ultimately comes to rest. Hence, acceleration a < 0.
