How does Newton's third law apply to a cannon?

Answer 1

Newton's third law: For every action, there is an equal and opposite reaction.

In a cannon, the cannon shooter should jerk backwards when it fires unless there is something holding it back. In that case, it will create either friction or some other energy, depending on the structure.

Newton's third law states that for every action, there is an equal and opposite reaction. In the case of a cannon, when it fires a projectile, the cannon experiences a force pushing it backward (recoil), while the projectile experiences a force pushing it forward. These forces are equal in magnitude but opposite in direction, as dictated by Newton's third law.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
