Good video about relative motion

a baseball is fired out of the back of a truck going 60mph at 60mph

The actual video clip is OK, but drawn out a bit. Why is the driver wearing a helmet, but not the guy in the back of the truck?

Thank you for sharing this video about relative motion. It is a great example of how objects can have different velocities and still appear to have the same motion to an observer. In this scenario, the baseball is fired out of the back of a truck traveling at a constant velocity of 60mph. The baseball also has a velocity of 60mph, but in the opposite direction. This is known as relative motion. To an observer standing still, the truck and the baseball would appear to be moving together at a combined velocity of 120mph. However, to an observer in another vehicle traveling at the same speed as the truck, the baseball would appear to be stationary. This concept is important in understanding the movement of objects in relation to each other and can be applied in various fields of science, such as physics and astronomy.
