The Body Fat percentage calculator will help you calculate the amount of fat stored in your body. It uses a method of measuring skin folds in seven different places on the body.

With this calculator you will calculate the geometric mean, also called the power mean of the zero order.

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.
