This calculator is used to determine the velocity of an object when it is released from a height or when work is done against gravity, given its potential energy and mass. The potential energy (PE) is the energy an object possesses due to its position in a gravitational field. The mass (m) of the object is its amount of matter.

The formula used for this calculation is derived from the law of conservation of energy, which states that the potential energy of an object at a height is converted into kinetic energy when it falls. The kinetic energy (KE) is given by KE = 0.5 * m * v^2, where v is the velocity of the object. Since PE = KE at the point of release, we have PE = 0.5 * m * v^2. Solving for v gives us v = √(2 * PE / m).

Enter the potential energy and mass of the object in the input fields and click the "Calculate" button to find the velocity. The result will be displayed in meters per second (m/s). You can reset the form by clicking the "Reset" button.
