Forces Acting on a Block on a Hill | Why Things Slide Downhill

Assemble a Free Body Diagram for a block on a hill. Combining, through Vector Addition, the Normal Force and the Force of Gravity (ie. Weight) it is possible to construct equations relating Gravity to the magnitude of the Normal force as well as the Net Force on the object down the hill.
The free body diagram of a block on a hill is a key idea when analyzing situations in both physics and engineering. This topic comes up in introductory STEM courses such as physics and engineering courses such as high school physics, AP Physics 1, AP Physics C and PLTW POE. This also serves as the foundation for many problems that appear on A Level Physics and the JEE.
