Materials required:
A ball, a marker or a chalk, a scale or a measuring tape and a stop watch or a clock.
Procedure:
- Draw a straight line on the ground with a marker or a chalk.
- Ask one of your friends to stand \(1\) to \(2\ m\) away from it.
- Let your friend gently roll a ball along the ground in a direction perpendicular to the line.
- Note the time at the moment the ball crosses the line and also when it comes to rest.
- Measure the distance between the point at which the ball crosses the line and the point where it comes to rest.
- You can use a scale or a measuring tape.
- Let different groups repeat the activity.
- Record the measurements in the given table format.
- In each case, calculate the speed of the ball.
