How Does Geometry Help Physics?

Hi, my name is Stefan. Today, I'm going to be speaking on how does geometry help in physics? Well, let's say we have a mass and it's on a hill. Now, if we know the incline of this hill, the degrees of it, we'll call it data. Geometry allows us to look at the force of gravity relative to this hill here. You know that a gravity is pushing downward this way. So, relative to this mass on the hill, we can find the horizontal force pulling on it, relative to the hill. And we can solve this G sine data is equal to the horizontal force, force H. And this is geometry and this is geometry used in physics.
