Newton's three laws and me
Newton's Laws:
Newton states three laws (1) objects at rest, remain at rest, objects in motion remain in motions until acted on by an outside force. Yes. my dog laying on the couch is an object at rest. when I push him off the couch he is acted up on by me, and gravity and falls (slowly) off the couch.
(2) acceleration of an object is related to the force acting on it--if I push my dog gently he will slide off the couch, but if I push him with more force he will fall with more speed. (3) when two objects interact the force acted upon object one by object two is in the opposite direction--when I push on my dog I am the force that is causing the collision. I don't continue on in the same direction as I push, but rather my body goes one way and my dog goes the other. Luckily I do not mind if my dog is on the cough and this is all theoretical.
Energy efficient culture!
Unfortunately we don't live in an energy efficient culture. IF we did, perhaps we would not be in the predicament we are with global warming and the accelerated melting of polar ice caps. but we do know that energy can neither be created or destroyed and we can utilize this on small scale practices like backyard gardening -- this is illustrated when we compost, we take nutrients from left over vegetables, plants (harvested energy from the sun) and let them decompose naturally, adding oxygen, nitrogen and carbon and it heats up and converts itself into useable energy--soil. the cycle continues

I really enjoyed how your dog can promote the law of inertia-
