What are newton's three laws?Show answer
A common Eduqas error is to treat a Newton's third law pair as the cause of equilibrium. The pair acts on different objects (for example the Earth pulls a book down, the book pulls the Earth up), whereas equilibrium of the book balances the weight against the normal force, which act on the same object.
