Circular Motion

This function calculates the relationship between circular movement, radius and time.

The circular motion is a movement of an object along the circumference of a circle. This function calculates the revolutions per second, the speed, the radius or the time required for one revolution.

To perform the calculation, use the radio button to select which value should be calculated. Then enter the required values and click the 'Calculate' button.

Formulas for circular motion

Rotational speed

The rotational speed is calculated from the circumference of the circular orbit and the time required for one revolution.

\(\displaystyle Rotational speed =\frac{circumference}{needed\; time} \;\; v=\frac{C}{t}\;\;=\frac{2·π·r}{t}\)

Duration of one circulation

To calculate the orbital period, the number of revolutions in a certain period of time is determined. The period of rotation is obtained by dividing the period by the number of revolutions.

\(\displaystyle Duration =\frac{needed\; time}{number\; of\; circulation} \;\; T=\frac{t}{n}\)

Frequence

The frequency or revolution speed is the reciprocal of the period of rotation.

\(\displaystyle Frequenz =\frac{number\; of\; circulation}{needed\; time} \;\; f=\frac{n}{t}\)
