Different disciplines, different priorities. While mathematicians count hairs and chemists worry about toxicity levels, physicists just want to calculate the trajectory of a child-sized projectile. Nothing says "practical application of F=ma" quite like launching a small human. I've personally used this approach to explain Newton's laws to undergrads who wouldn't stop texting during lecture. Suddenly everyone's paying attention when you start discussing optimal launch angles.
