The Force Factor
The concept of forces is one of the most fundamental ideas in science and is reflected in science education from an early age. Children don’t start learning about forces in school, of course, but as soon as they start to move. They learn, first-hand, how to use force to make themselves move and to stop moving. They learn that friction slows things down and that this is sometimes a good thing and sometimes a nuisance. They learn that everything falls to the ground unless prevented.
