Explain an activity to observe where speed and direction of motion change continuously.

Explanation

1) Throw a stone into air by making some angle with the horizontal.
2) The path of the stone and velocity vectors are as shown in the figure.
3) Here we observe that the speed of stone is not uniform as it traverses different distance at different intervals of time and finally comes to rest.
4) The direction of motion is also not constant, as shown by the velocity vectors.
5) In this activity, we noticed that the speed and direction of motion both change continuously.
