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.

Use the Ishihara test to check if you suffer from color blindness, to what extent your defect is Protanopia or Deuteranopia, or maybe just insufficient differentiation between red and green shades. As a result, in addition to the diagnosis, you will have the opportunity to check how each of the Ishihara plates is seen by people with various visual impairments, and if you have a defect, they will allow you to see what is on the plates.
