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 ...

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 ...

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 ...

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 ...

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 ...

Figure 1: Formation of Copernicus crater by a low-speed impact. Figure 3: Impact velocity distribution on the Moon. The planetary geology community has not previously considered the possibility that ...
