5 OF THE BEST DEMOS OF PROJECTILE MOTION AND ITS QUIRKS
JUMPING ON A trampoline sounds pretty fun. Jumping on a trampoline while it’s rolling down a dirt road looks even cooler. That’s exactly what Dunkin Devils, a stunt team based in Slovenia, did in a recent Instagram post. It looks so awesome, it almost seems impossible. Of course, it’s not magic—it’s just physics. In particular, it’s a great example of projectile motion.
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 tennis ball you loft across the room is projectile motion. Flipping a coin—the center of mass is in projectile motion. As you can probably guess, a dude jumping on a moving trampoline is also an example of projectile motion.
For these kinds of motions, the following must be true:
