This means the acceleration is always pointing downward ! Galileo observed that all objects fall with the same, constant acceleration g = -9.80 m/s 2 (downward) (as long as air-resistance is small)

2 Introduction Projectile Motion 2 special cases of 1d-motion: motion with constant velocity (e.g. horizontal motion on a frictonless rail) motion with constant acceleration (e.g. free fall) Projectile Motion is combination of horizontal constant velocity and vertical free fall 2d-Motion Motion in the horizontal and vertical directions are independent .

    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.
