Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

In this video, we introduce the fundamentals of kinematics in 2D, focusing on projectile motion. Learn how to break down the horizontal and vertical components of motion, apply key equations, and ...

College football season is coming to an end (I guess technically, the season is over - it is bowl season). Anyway, this is something I wanted to do a long time ago, but I kept getting side tracked. If ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

A boy kicks a ball horizontally over the edge of a cliff with a speed of \(6ms^{-1}\) as shown in the diagram. The ball hits the surface of the water \(3s\) later. (a) Calculate the vertical speed of ...

Projectile motion Imagine throwing a ball to someone. As the ball travels horizontally through the air, it also travels vertically because of the effects of the force of gravity. Any object moving in ...
