How far is the storm? How close is lightning? Is the storm looming or is it moving away? Surely everyone has asked themselves such questions. That is why we have created a lightning distance calculator with which you can easily check it.

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.

With this calculator you can quickly calculate the centrifugal force. You will also calculate the mass of the body from velocity, radius and force, the radius of the circle given the mass of the body, the force and speed and the speed of the object moving in the circle given the given force, mass and radius.
