General Physics Dr. Brahmia 1 KINEMATICS IN TWO DIMENSION Projectile Motion Projectile motion is the motion of an object fired at an angle with the horizontal. This motion can be discussed by analyzing the horizontal (x) component of the objects motion independently of the vertical (y) component of motion. cos 0 0 v v x sin 0 0 v v y KINEMATICS IN TWO DIMENSION... Projectile Motion... If air resistance is negligible, then the horizontal component of motion does not change constant velocity motion The following equation describes the horizontal motion of a projectile. t v x x x 0

General Physics Dr. Brahmia 2 KINEMATICS IN TWO DIMENSION... Projectile Motion... The vertical component of motion is affected by gravity uniform constant acceleration motion The motion is then described by the equations for an object in free fall. The following equations are used to describe the vertical motion of a projectile.

### 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.
