1. Point mass downfall

1.1 Purpose of experiment

The object falling on the curvature is off-bending in a moment and goes the free-fall. In theory, calculate the falling point of object and review the results as compared to the measuring values.

2.3 Theory

2.3.1 Center of mass
The center of mass or mass center is the mean location of all the mass in a system. In the case of a rigid body, the position of the center of mass is fixed in relation to the body. In the case of a loose distribution of masses in free space, such as shot from a shotgun or the planets of the solar system, the position of the center of mass is a point in space among them that may not correspond to the position of any individual mass.

Let`s think about causes of errors

- It is impossible to measure period exactly. We get data by using people`s sense Result depends on the data which is measured by each person. So we couldn`t get accurate measurements. It makes big error. Using the machine is better than people`s sense.
