# Normal Force Calculator - For Horizontal Surface Online

### Normal Force Calculator - For Horizontal Surface Description

The formula for calculating Normal Force Calculator - For Horizontal Surface is

=> External Force : No

Normal Force = mass * g

=> External Force : Downward

Normal Force = m * g + F * sin(x)

=> External Force : Upward

Normal Force = m * g - F * sin(x)

Example of Calculations:

External Force: none

mass: 3 kg

FN = 3 * 9.8 = 29.42 N

External Force: Downward

mass: 4 kg

outside force: 23 N

Angle of the outside force: 5 degree

FN = 4 * 9.8 + 23 * sin(5) = 41.23 N

External Force: Upward

mass: 4 kg

outside force: 23 N

Angle of the outside force: 5 degree

FN = 4 * 9.8 - 23 * sin(5) = 37.22 N
