Why is 1.2g the Hypotenuse on an Inclined Plane?

Click For Summary
SUMMARY

The discussion centers on the use of 1.2g as the hypotenuse when resolving forces on an inclined plane in physics. Participants clarify that when resolving a vector into components, the vector itself serves as the hypotenuse of the right triangle formed. This distinction is crucial to avoid confusion between the geometry of the inclined plane and the vector resolution process. The reference to "Inclined Planes" provides additional context for understanding this concept.

PREREQUISITES
  • Understanding of vector resolution in physics

Homework Statement


When resolving forces on an inclined plane, can anyone explain to me why 1.2g in my pic is used as the hypotenuse? It looks intuitively like it should be the opposite or adjacent.

Thanks for any help :)

Whenever you resolve a vector into components that vector will be the hypotenuse. (Don't confuse the triangle of the inclined plane with the triangle you need when resolving a vector.)
