Write down the type of motion of a body in each of the following distance time-graph.
The slope of the distance-time graph at any point gives______.
The slope of the distance-time graph indicates the speed.
Assertion: The slope of the distance-time graph of a body moving with high speed is steeper than the slope of the distance-time graph of a body with low velocity.
Reason: Slope of distance-time graph = speed of the body.
What do you infer if
- Distance – time graph is a straight line.
- The velocity-time graph is curved.
- Displacement time is zigzag.
