Book Free Demo- Take a heavy ball. Drop it on a thick bed of sand. A wet bed of sand would be better. Drop the ball on the sand bed from height of about \(25\ cm\). The ball creates a depression.
- Repeat this activity from heights of \(50\ cm\), \(1\ m\) and \(1.5\ m\).
- Ensure that all the depressions are distinctly visible.
- Mark the depressions to indicate the height from which the ball was dropped.
- Compare their depths.
- Which one of them is deepest?
The ball from the height made most deepest depression.
- Which one is shallowest?
The ball from the height made most shallowest depression.
- Why?
the height, deeper the depression.
- What has caused the ball to make a deeper dent?
The reason being for deepest bend is the height of the ball is to the depression.
- Discuss and analyze.
A moving object can do work. An object which is moving faster can do than the same object moving comparatively slow.
Here when ball drops, Its is converted into and finally resistive force offered by sand stops the ball.
