Projectile Motion and Drag

0:00 Introduction
0:18 Projectile Motion simulation
0:35 Assumptions (no drag, only gravity)
1:01 x direction (constant speed)
1:17 y direction (9.8 m/s/s)
1:49 Lets add drag
3:14 Vx is not constant

This video explores some of the assumptions that are made when solving projectile motion problems in physics, including the idea that there is no drag acting on the object. With a simulation, the motion of a projectile (with drag acting on it) is illustrated. As illustrated in the simulation, the velocity in the horizontal direction is no longer constant.
