# Physics calculators

### Density, mass, volume

With this calculator you can calculate the density of the substance, i.e. specific mass. The calculator will also help to determine the mass of the substance and the volume it occupies.

### Force, mass and acceleration calculator

With this calculator you can calculate the force, mass and acceleration from Newton's Second Law of Motion.

### Kinetic energy calculator

With this calculator you can quickly calculate the kinetic energy of an object. You will also calculate mass from energy and velocity and speed given kinetic energy and mass.

### Vertical projectile motion - speed, time, height

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.

### Brinell hardness scale

With this calculator you can calculate the HB hardness or the hardness of metals based on the Brinell hardness test.

### Gravitational acceleration

With this calculator you can calculate the gravitational acceleration of a body pulled by another body. The calculator will also help to calculate the distance between the centers of the attracting bodies and the mass of the body producing the gravitational field and attracting the body for which the gravitational acceleration is given.

### Centrifugal force

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.

### Centripetal force

With this calculator you can quickly calculate the centripetal 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.
