The potential energy of an object in the gravitational field is calculated
from the altitudinal position of the object and its mass.
It is defined as the work needed to rise the object by this height.
U = m g h
With this calculator you can calculate the potential energy U
with a given mass m and a given
height h. Calculations vice versa are also possible.
A value of 9.80665 m/s² is used for the gravitational acceleration.
Usage:
Always choose the correct unit in the corresponding pulldownmenu
before you type a value.
Type the given values into the corresponding fields.
After a mouse click on any free space of the window or the
"calculate"button the calculation is performed.
The fields with the input quantities have a light green background, the background
of the output quantities is colored pink.
For another calculation with a value that has been calculated before, click on the
radio button in front of the value. The line with this quantity will be recolored
light green and become input value for the next calculation. The calculation is
always performed with the two quantities changed last.
Click on the "reset"button to reset the calculation.
Mont Ventoux.
Example:
Two cyclists (65 kg and 80 kg) want to ride from Bédoin to the top of
Mont Ventoux (1912 m). The gain in altitude
is 1610 m. How much more energy the heavier rider has to provide?
Type the mass difference (15 kg) and the height gain (1610 m) into the corresponding fields.
After the next mouse click on any free space of the window or the
"calculate"button you can read the value of the potential energy (e.g. 236.8 kJ).
In the pulldown menu for the energy unit you can also choose another unit
(e.g. 56.6 kcal). However, the result is based on the height difference only.
Friction and similar effects are not considered.
Remarks:
 Please note the remarks about the
representation of numbers..
