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.
When we neglect friction we notice that the body moves downwards. image 2
