This week in Physics we talked about 2D Kinematics, and
projectile motion. Projectile motion directly relates to the Vegas rule. “What
happens in Vegas stays in Vegas.” This rule tells us that the axes are
independent. What happens on either axis stays on that axis. Solving 2D
kinematic problems is generally the same as 1D kinematics, except you must
solve for variables on the x and on the y. We use the same equations provided
for us form the “equation board not bored.”
For example, in the following video I rolled the ball off
the table, which is 1 meter high. The ball was rolled with an initial velocity
of 3m/s. How far from the table did the ball land?
The ball landed 1.92 m away from the table.
