Question

The speed-time graph of an object moving in a fixed direction is shown in figure 2.E4

The object

• A. is at rest
• B. is moving with fluctuating speed
• C. moves with constant speed
• D. moves with non zero acceleration

Answer 1

The correct option is C

moves with constant speed

1. We can calculate the acceleration by looking at the graph line.
2. As the graph is a straight line, the slope is constant.
   
3. The graph line moves parallel to the axis.
4. As time changes, in the graph, the speed remains constant.
5. so the object moves with constant speed.

Hence, option C is correct
