*Newton's laws* form the foundation of [[classical mechanics]]. They state that 1. A body will continue to move uniformly until a force acts on it. 2. The force on a body is given by the change in [[momentum]]. If the mass does not change (you are not describing a rocket), the law simplifies to $F=m\cdot a$, where $F$ is the force, $m$ is the mass and $a$ is the acceleration. 3. Every force causes an equivalent force in the opposite direction (actio=reactio). These three principles were formulated by Isaac Newton around 1687 and play a central role in the theory of motion. >[!read]- Further Reading >- [[Classical Physics]] >- [[Classical Mechanics]] >[!ref]- References
