The inclined plane is studied by mechanics and, to calculate it, we use Newton's Second Law.

Is a block of mass “m” supported by an inclined ramp at an angle? with respect to the horizontal plane. Despise the friction.

Forces acting on the body are:  image 1

P: Force weight = P = m.g

Where: g = 9,8 m / s2

m = body mass given in kg.

FN: Normal reaction force to the plane.
