The Physics of Sales

Many schools are closed so I thought it might be time to revisit a course many of you might recall from high school or college…physics; the science of matter, motion, and energy.

Well, sort of physics…the physics of sales. What? The physics of sales? Yep…that’s what I wrote. Consider this famous quote from Sir Isaac Newton.

“A body in motion tends to stay in motion unless acted on by an outside force”

If a body at rest tends to stay at rest and a body in motion tends to stay in motion, then why does any object when thrown just stop moving a few seconds after it hits the floor?

Stay with me…there’s a point here!

A body at rest stays at rest because it is not being moved and a body in motion will stay in motion because there is a lack of friction or some sort of force, like gravity, or an obstacle to stop the body.

Remember that Newton’s law says that the body will stay in motion until it is acted upon by some opposing force. In this question, the reason the body loses some of its energy is because when it hits the floor it loses some part of its energy since the collision is inelastic and further it is acted upon by its weight and air friction. So gradually the heigh
