Question

State the type of motion represented by the following sketch in the figure. Give an example of the type of motion.​

Answer 1

Slope velocity-time graph​
In velocity time graph, velocity is plotted along Y-Axis and time is taken along X-axis. Since acceleration is the ratio of change in velocity and time taken, therefore the slope of velocity-time graph gives acceleration.
From the above graph,
Slope $=\frac{\text{Change in velocity}}{\text{Change in time}}=$ acceleration
Inference from given velocity-time graph​
Here, the velocity-time graph is a curved line with decreasing slope so, the body is moving with non-uniform retardation.​

Example: A car reaching its destination, or the motion of an object dropped in water.​
