What is Newton's Third Law?

• Every body perseveres in its state of rest or uniform and rectilinear motion unless compelled to change its state by forces impressed upon it.

• With every action there is always an equal and opposite reaction: That is, the mutual actions of two bodies are always equal and directed in opposite directions

• The change of motion is proportional to the motive force impressed and occurs along the straight line along which that force is impressed.
