pov : you have test in an hour

You are my hero bro.. You are helping me in everything since 3 years..(I am watching your videos since 3 years) You made my High School and Now Engineering super easy..!! Thank You Soooooo Much..!!!

Physics is the bane of my existence.

Bro you explained in the first two minutes what ive spent 2 entire periods listening to my teacher and trying to figure out God bless broooo

My exam is in 20 minutes and I'm watching all the math vector vids I can find LOLLLL I'm screwed.

he teaches better than my ap teacher that went to harvard

You might be wondering: why is Fn = mg cos(a)? The y-component of the gravitational force always acts in the opposite direction of the normal force Fn, thus cancelling each other out since their magnitude needs to be the same. Why is the magnitude of Fn and of the y-component of the gravitational force the same? Simple: because the object isn't moving upwards or downwards in that perpendicular line shown in the video. (relative to the plane) Why is Fg = mg sin(a)? Fg is the force that is equal in magnitude and also direction with the x-component of the gravitational force (F=mg); since they are parallel to each other and point in the same direction, their magnitude is the same. The x-component of the gravitational force is what's causing the object to slowly slide down.
