Unformatted text preview: inclined plane. Fg = ma the force of gravity, where a is the force of acceleration due to gravity. Fn Fg the force perpendicular to the direction of motion (the inclined plane). Also called the normal force, always acts in a direction perpendicular to the surface. Fn is the force that the ramp applies to the object to keep the object on the ramp Now, we resolve the force of gravity into two components of force. One force II to the inclined surface Fn One force I to the inclined surface F II Fg = FI + FII θ Fg FI FII FI balances the force. This leaves as the...
