- Newton's First Law of Motion- The Law of Inertia: An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.Explanation: According to the law of inertia, a ball rolling down a hill will continue to roll unless friction or another force stops it.
- Newton's Second Law of Motion- The Law of Force: The acceleration of an object depends on the mass of the object and the amount of force applied.Explanation: When the same force is applied to two objects, the one with less mass will move faster. Thus, the shelf without books would move faster than the shelf with books.
- Newton's Third Law of Motion- The Law of Action/Reaction: Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.Explanation: The weight of the books is acting in the downward direction on the table (action). While the reaction acts in the upward direction on the books.
