It is that FIRST Robotics competition time of the year. Basically, in FIRST, high school students work in teams to build robots that compete in specific tasks. Apparently, this year a task involves ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

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 ...

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 ...

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 ...

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 ...

As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity. The only force acting on the object is gravity, causing it to ...

Physics derivation of the range equation for projectile motion—understand how the formula for maximum horizontal distance is derived from fundamental principles. This video walks through the kinematic ...
