Things That Are True - Newton's Laws

"Newton's First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it."

"I'm hiding, Mommy. You don't see me."

"A body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force."

"If a body experiences an acceleration ( or deceleration) or a change in direction of motion, it must have an outside force acting on it. Outside forces are sometimes called net forces or unbalanced forces."

"The Second Law of Motion states that if an unbalanced force acts on a body, that body will experience acceleration ( or deceleration)."

Today was a day of unbalanced, outside forces, if you define outside forces as sunshine, fresh air, and the irresistible appeal of things that need climbing. Which I do.

All that business about Newton's laws was scanged from this NASA page, because yay science!
