Physics: calculating force of friction
The tutor shows a basic example of calculating friction. The force of friction, Ff, on a flat surface is given by Ff = μFN where μ = coefficient of friction (often looked up from a table, or given) FN = …

Physics: calculating the normal force on a slope
Tutoring physics, you cover this every year. The tutor offers a quick guide. The normal force (FN) refers to the gravitational force perpendicular to the surface an object sits on. If the object sits on a level surface, the normal …
