Shift of the center of gravity and its effects in Gravitation – Class 9 Science Experiment
Chapter Name: Gravitation
Activity Name: Shift of the center of gravity and its effects in Gravitation
Activity Description:
This experiment aims to explore the concept of the center of gravity and its shift when changing body positions.
The activity involves attempting to touch one’s toes while standing erect and repeating the same action while standing against a wall. The purpose is to observe and understand how the center of gravity affects balance and stability in different positions.
Required Items:
- A wall (or any vertical surface)
Step by Step Procedure:
- Stand erect on a flat surface.
- Attempt to touch your toes without any support (Fig-20(a)).
- Next, stand against a wall with your back against it.
- Try to touch your toes in this position as well (Fig-20(b)).
Experiment Observations:
- Note whether you were able to touch your toes in both positions or not.
- Observe any differences in the ease of touching your toes between the two positions.
- Pay attention to the sensations and balance of your body during the experiment.
Precautions:
- Ensure the area is clear of obstacles to prevent any accidents.
- Perform the experiment on a flat and stable surface to ensure safety.
- If needed, have someone supervise the experiment, especially if the participant has balance issues.
Lesson Learnt from Experiment:
Through this experiment, participants will learn about the significance of the center of gravity in maintaining balance and stability. When standing erect, the center of gravity is typically closer to the body’s base and is easier to control.
However, when standing against a wall, the center of gravity shifts outward, making it more challenging to touch the toes. This activity helps to comprehend how altering the position can affect the center of gravity and its effects on the body’s stability.
