Calculation method

Calculation method

Centripetal force (N)

a × b × b ÷ c

Centripetal acceleration (m/s²)

b × b ÷ c

Symbols and units
a
Mass (kg)

c
Radius (m)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Required net inward force for uniform circular motion; it is not an additional force type.
