... mΔv = m (v f − vi ) = mv f − mvi mΔv = p f − pi mΔv = Δp In this equation, the ball’s initial momentum is pi (= mvi) and the final momentum is pf (= mvf). Therefore, the equation for Newton’s second law can be written as the following ratio: Δp F= Δt This equation states an alternative, equivalent f ...

... The length of one “atomic spring” is about one nanometer (10−9 m). The number of atoms in a typical solid such as a book or a table is about 1,000,000,000,000,000,000,000,000 . When you push on a solid, the atomic springs compress, i.e., the electron clouds of the atoms overlap. The harder you push, ...
