General Physics I - 2D Motion Components of motion (w/o resistance) Projectile Motion g (down!!) Range = (v o 2 sin 2 )/g v x = constant v y = changes due to g v y = 0 at max height (h) v xo = v o cos & v yo = v o sin note: v o = (v xo 2 + v yo 2 ) ½ x = v xo t & y = v yo t for constant acceleration due to gravity (g): x = v xo t + ½ a x t 2 y = v yo t + ½ a y t 2 v x = v xo + a x t v y = v yo + a y t Vectors: A + B = B + A (Triangle Method) subtraction === A - B = A + (- B ) : a negative sign refers to the opposite direction * or / = change magnitude (direction if there is a negative #)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
