What is Newton's laws of motion?
[[File:Newtons laws in latin.jpg|thumb|Original publication of the first two laws, in Latin]] [[Isaac Newton]] (1642–1727) is widely known as the father of [[dynamics]], the study of [[movement|motion]]. He developed three laws that are the foundation of [[classical mechanics]]. They are believed to be true because the results of [[experiment]]s by scientists agree with this. == First law (sometimes called [[inertia]]) == *If a body is at rest it remains at rest or, if it is in motion, it moves with uniform velocity, until it is acted on by a [[resultant force|net force]].<ref>{{Cite web|title=Newton's laws of motion {{!}} Definition, Examples, & History {{!}} Britannica|url=https://www.britannica.com/science/Newtons-laws-of-motion|access-date=2021-11-19|website=www.britannica.com|language=en}}</ref> Alternatively, everybody in this universe will be in a state of rest or uniform motion unless acted upon by an external force or otherwise. From the above statement, it's clearly observable that Newton's first law defines force and inertia. This law also gives the Qualitative definition of force. <ref>{{Cite web|title=Newton's First Law of Motion|url=https://www.physicsclassroom.com/class/newtlaws/Lesson-1/Newton-s-First-Law|access-date=2021-11-19|website=www.physicsclassroom.com}}</ref> A ''uniform velocity'' means that an object moves at a constant speed without changing direction (i.e. in a straight line). A ''net force'' means that the forces acting on the object are not balanced. In other words, the first law states two things: #A stationary object will only begin to move if there is an unbalanced force acting on it. #A moving object will only change speed or direction if there is an unbalanced force acting on it. The first part states that a table resting on the ground will not move unless pushed. Although [[gravity]] is acting on the table, pulling it down, there is a ''reaction force'' from the ground which is pushing it back. The forces acting on the table are ''balanced'', so the object will not mov
