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 ...

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 ...

The terms projectile and trajectory are introduced. Projectile Motion: The terms projectile and trajectory are introduced. Students learn to describe horizontal and vertical components of a projectile ...

In the previous section we have seen that a projectile will follow a very predictable curved path in air. However when the projectile is given a greater speed, it goes further. The reality of the ...

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 ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...
