Provide the basis for Newtonian mechanics. Based on three laws, describes realtionship between motion of objects and how it is affected by forces acted on it. ## First law >"A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force" ## Second law >"The net force on a body is equal to the body's instantaneous acceleration multiplied by its instantaneous mass or, equivalently, the rate at which the body's momentum changes with time" ## third law >"If two bodies exert forces on each other, these forces have the same magnitude but opposite directions" ## 🔗Resources - https://en.wikipedia.org/wiki/Newton%27s_laws_of_motion
