Forces at Angles (No Friction)

How to find normal force or acceleration for problems where there is a force at an angle but there is no friction. These physics problems can be difficult because the vertical component of the applied force either increases or decreases the normal force. This video goes over how to find the normal force when there is a force applied at an angle. Example problems with solutions are shown. These problems are common on the AP Physics C: Mechanics test as well as AP Physics 1 exam.

Exercises with angles are ALWAYS interesting to solve....Great video !!

Haven't been getting this chapter for a while. Glad I checked this video out!!

this video helped me with exactly what I needed. This and the forces at angles with friction, thank you fr

“Heh, normally” actually had me crackup 😂

I don't get how u got the 10m/s ^2 in the first question but i def learned alot ❤❤

The 2nd question seems wrong to me, it should be negative fsin(thayta) not positive. In your (with friction video) you made fsin(thayta) negative. Why?

Guys stop it with the "gee thanks man"
