You observe its orbit at points A, B, C, and D. a) Draw vectors that represent the asteroid's Net Force and its Parallel & Perpendicular change in momentum at each point. {{youtube>eLC6Opx_zyk?large}} ---- Part 2: At point A, your asteroid is 1.5 e 10 m away from the center of Earth. At point C, it's 2.0 e 11 m away. Calculate the Force of Gravity at both of these points, then the perpendicular change in momentum and the force of uniform circular motion at A & C. {{youtube>4pbiDvh3eF0?large}} === Four Quadrants === {{183_notes:examples:momentum_change_and_fpar_fperp_quadrant.png}} 183_notes/examples/videoswk6.txt Last modified: 2016/08/17 19:02by waterso8
