Horizontal Motion: Uniform 1 2 3 4 5 Equal Distances Rolling ball (with no friction) is an example of uniform motion. Velocity of the ball is constant so distance between “frames” (equal time between frames).

Free Fall: Accelerated Vertical Motion 1 (Release) 2 3 4 1 3 5 7 1 4 9 1 6 Free Fall is an example of accelerated motion. Total distance from point of release increases in the ratios 1 : 4 : 9 : 16 : 25 : … or 1 2 : 2 2 : 3 2 : 4 2 : 5 2 Distance between frames increases as 1 : 3 : 5 : 7 : 9…

    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.
