To calculate frictional force, we need to know the acceleration and mass.

Frictional force can be calculated using the following formula:

**Frictional Force (F) = Acceleration (a) × Mass (m)**

Where:

F: Frictional Force (in Newtons - N).

a: Acceleration (in meters per second squared - m/s²).

m: Mass (in kilograms - kg).

Use the following calculator to calculate frictional force based on acceleration and mass.
