WOW!!!! 😮 INERTIA - PHYSICS is really AMAZING!!! 😃

By NEWTON'S FIRST LAW (Inertia), we know that a body with constant velocity moving in a straight line tends to stay in that motion. It is exactly the case of the boy who is jumping on the trampoline. Since the trampoline moves in a straight line with constant speed, the boy also moves in a straight line with that speed. From the point of view of whoever is in the truck, this guy only moves up and down. From the point of view of someone standing outside the truck, its trajectory would be approximately parabolic curves. PHYSICS is really FASCINATING. 😉
