 A Man & His Horse...................................... Man: Giddy up! Pull the cart so we can get going. Horse: For me to pull the cart would be a futile effort. You see, if I pull on the cart, the cart will pull back on me. By Newton's 3rd law... The forces are equal and opposite so they'll cancel out. A zero net force wont work. Man:(thinking...) I don't care bout the force exerted on you! I'm interested in the force you exert on the cart. You pull the cart and I guarantee it will move. Horse: But how can I move forward when the cart pulls backward on me. Man: (thinking...) just push backward on the ground. By Newton's 3rd law, the ground will push forward equally on you. Then I'll simply follow. Seconds later... Man: Hahaha....The ground is doing a great job! Horse: Physics...grumble...Physics!!! The first step in the acquisition of wisdom is SILENCE, the second is LISTENING, the third MEMORY, the forth, PRACTICE and the fifth is TEACHING others!modified 14-Nov-12 12:18pm.
