Chapter Name: Gravitation
Activity Name: Balancing of spoon and fork in Gravitation
In this experiment, we will fasten a fork, spoon, and wooden matchstick together in a specific manner. When the combination is placed on the edge of a glass, it will surprisingly balance steadily. We will explore the scientific principles behind this peculiar balancing phenomenon.
- Wooden matchstick
Step by Step Procedure:
- Take the fork and spoon, ensuring they are clean and dry.
- Place the wooden matchstick parallel to the handle of the fork.
- Attach the spoon to the other end of the matchstick, creating a straight-line arrangement of fork-matchstick-spoon.
- Make sure the matchstick is securely attached to both the fork and spoon, so they form a rigid structure.
- Place the balanced fork-matchstick-spoon combination on the edge of the glass.
- Observe that the combination remains balanced and does not fall off the glass’s edge, seemingly defying gravity.
- Handle the fork, spoon, and matchstick carefully to avoid any damage during the experiment.
- Ensure that the matchstick is firmly and symmetrically attached to the fork and spoon to achieve proper balance.
- Perform the experiment on a stable surface to prevent accidental spills or tipping over of the glass.
Lesson Learnt from Experiment:
This experiment demonstrates the concept of the center of gravity. When the fork, spoon, and matchstick are arranged in a particular way, the combined center of gravity of the system is positioned precisely over the edge of the glass, allowing it to balance effortlessly. This equilibrium occurs due to the force of gravity acting on the object’s mass at a single point, enabling it to stay in a stable position.
