Kinetic energy and momentum
The kinetic energy of an object is the energy it posseses due to its motion. It is defined as the work needed to accelerate the object of a given mass to its velocity. There are the following equations in classical mechanics for kinetic energy and momentum.
P = m v
With this calculator you can calculate the kinetic energy Ekin and the momentum P of a mass point from a given mass m and a given velocity v. Calculations vice versa are also possible.
Always choose the correct unit in the corresponding pull-down-menu
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.
Together with his bicycle a cyclist has a mass of 85 kg. What must be his velocity,
so that his kinetic energy amounts 1 kcal (or, to which speed must he accelerate
from zero, that, without considering any friction etc., the work done amounts 1 kcal)?
