(b) The same player exerts an identical force on a stalled SUV and produces a far smaller acceleration (even if friction is negligible). (c) The free-body diagrams are identical, permitting direct comparison of the two situations.

Muscles, for example, exert far greater forces than we might think. Figure shows a forearm holding a book and a schematic diagram of an analogous lever system. The schematic is a good approximation for the forearm, which looks more complicated than it is, and we can get some insight into the way typical muscle systems function by analyzing it.

Newton’s Second Law of Motion: A principle stating that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.

This chapter explores the nature of these forces, the factors affecting them, and their dual role as both beneficial (enhancing traction and grip) and detrimental (causing wear and reducing energy efficiency).
