Gravitational Force

Gravitational Force

Observe: What happens when two objects of the same shape but different mass are released from the same height.
Infer: That all objects fall at the same rate, regardless of their mass.

Aim: To observe the effect of gravity on objects.
Materials: A small rug, two similar plastic bottles (one filled with water, the other is empty), low chair.

Procedures
1. Work in pairs. Place the rug on the ground.
2. Hold both bottles, one in each hand. With your arms stretched out in front of you,
    drop both bottles at the same time. Observe how they fall.
3. Now stand on low chair. Drop both bottles again with your arms outstretched.
    Observe how they fall.

Observations
1. When we drop the two bottles the first time, both of the bottles fall at the same time.
2. When we drop the two bottles again while standing on the chair, the bottles also fall
     at the same time.


Conclusion
 All objects fall at the same rate, regardless of their mass.
