“A body at rest tends to remain at rest, or a body in motion tends to remain in motion at a constant speed in a straight line, unless acted on by an outside force.”
That’s the first of Newton’s three laws of motion. And I instinctively remember that particular law every time we start out in a car. Anything unsecured in the back seat could hurt one of us if we had to stop suddenly.
Right. That reminds me of a CHP officer who told me in about 15 years of work, he never unbuckled a dead person. About a year later he told me that he had to unbuckle a dead person. That individual was killed by an unsecured passenger from the back seat.
