About Reaction Force Calculator (Formula)
The force is calculated using the formula:
where 9.81 is the acceleration due to gravity, and cos(angle) is the cosine of the angle.
angle = angle * (Math.PI / 180)
It then calculates the force by multiplying the mass by 9.81 and the cosine of the angle. The result is then displayed on the page as “Reaction Force: [result] N”.
Note: It is important to keep in mind that the force is acting perpendicular to the surface, so it is also calculated using the cosine of the angle between the force vector and the surface.
