REBOUND HEIGHT
Procedure
1. Read the procedure and the safety information, and complete the lab form.
2. Drop a large rubber ball from about 15 cm above a table.
3. Measure and record the ball's rebound height using a meterstick.
4. Repeat steps 2-3 with a small rubber ball.
5. Hold a small rubber ball on top of, and in contact with, the large rubber ball.
6. Release the two rubber balls from the same height, so that they fall together.
7. Measure the rebound heights of both rubber balls.
Analysis
8. Describe the rebound height of each rubber ball when it is dropped by itself.

Displacement = 0
Explanation:
Displacement can be defined as the straight line path distance between starting and final position.
The fog starts at 0 add moves 18 cm. Then moves 6 cm backwards and then another 12 cm backwards.
It is a vector quantity. We will take forward direction as positive and backward as negative
Displacement = 0 + 18 cm -6 cm - 12 cm = 0
Hence, the frog's displacement is 0 which means that frog came back to its initial position.
