Abstract
The experiment consists of three experiments. One of them is to test the law, and the other two are to measure the values experimentally ​​that can not be obtained theoretically.

In the point of mass downfall experiment, we use a ball with an IMU sensor. We drop the ball on curvature at three difference height of position and measure the distance of falling point. Using this geometrical value we will compare with the theoretical values. There will be difference in value. We find the reason of difference and a way to reduce it.

Introduction
Everything has some kinds of energy. In this experiment we compare theoretical and actual result of falling ball's energy conservations. If we drop the ball at ⓐ point in <Figure 1>, energy of ball is changed such as kinetic, potential and rotational.

<Figure > Path which the ball moves along the slope

If we assume there is no friction, no rotation and energy loss, we can use energy conservation equation.
