# Online Calculator: Force, Energy, Power

This calculator calculates the relationship between force, power and energy (work) both in the form of mechanical movement and heat retention.
Refer to our webpage for Work for a detailed description of these properties.

Force is the load required to achieve the desired rate of movement (or change in direction) of a given mass; measured in Newtons (kg.m/s²).
Energy is the distance over which the above force is applied, irrespective of time (from time=0 to time=t); measured in Joules (kg.m²/s²).
even KE is dependent upon distance: KE = ½.m. = ½.m.a.d = F.d

Power is the rate of release in the above energy per unit time; measured in Joules per second (kg.m²/s² / s).

All calculations are performed in metric units, which can be converted using CalQlata's downloadable Unicon calculator or our online Unicon calculator.

### Work Energy

This calculation is to determine the energy and power input required to move a mass;
a) through a medium, such as air or water, and;
b) accelerated up (or down) a slope (note: s=1 means an angle of 45°).
Should you wish to ignore the medium - accelerate through a vacuum - set the medium density to zero (ρ=0).
Should you wish to ignore the slope - move the mass over an horizontal surface - set the slope to zero (s=0).
Should you wish to ignore friction - between the mass and the supporting surface - set the coefficient to zero (Cf=0).

This calculation is based upon a constant acceleration over distance (d) and time (t).
The final velocity is along the inclined surface.
Whilst vertical acceleration - overcoming gravitational acceleration induced by the slope - is included in the calculation, it is assumed that the mass is supported vertically by a flat, inclined surface; i.e. g is accommodated by this flat surface.

### Rotary Energy

This calculation determines the following properties of a shaft being driven at constant speed:
torque; a force applied at a specified radius, which may be at the surface of the shaft or any other radial distance from its centre of rotation.
energy; the total amount of power to drive the shaft over the period of time 't'.
power; the rate of energy release required to achieve the input properties.
rotations; the total number of shaft revolutions in time 't'.

The mass of the shaft is unimportant in these calculations as it is assumed that it is supported in bearings. However, the force (F) is sized to overcome inertia and resistance.

### Heat Energy

This calculation determines the heat energy (EME) in a mass of matter at a specified temperature.
The atomic energy is the total kinetic energy of all the electrons in a single atom at the temperature entered.
The heat energy is the total kinetic energy of all the atoms in the mass at the temperature entered.
The temperature of any atom, is the temperature associated with the heat energy in the electrons orbiting in its innermost shell; Shell-1

It is important to spell the name of the atoms correctly (in the English language); e.g. sulphur not sulfur, otherwise the calculator will not understand and therefore fail to calculate.
The list on the right-hand side of this page provides the spellings that this calculator will recognise. You may copy and paste names from the list into the input boxes (upper and lower cases are ignored).

You may enter a percentage value for all of the elements you wish to include, but if your values do not equal 100%, you will receive an error message.
If you leave one value empty, the calculator will fill it in for you.
If you leave more than one percentage box empty, the calculator will share the missing amount equally between the empty percentages.

A typical aplication for this calculation would be to determine the amount of energy that would be needed to heat a substance from one temperature (Ṯ₁) to another (Ṯ₂): You would first enter "temperature"; Ṯ₁ and get the note resultant "heat energy"; E₁
You would then enter "temperature"; Ṯ₂ and get the note resultant "heat energy"; E₂
The energy (E) required to raise the temperature of the substance from Ṯ₁ to Ṯ₂ is; E = E₂-E₁
