Detailed explanation-1: -Outside force: Newton’s First Law states that objects at rest stay at rest unless acted upon by an outside force. In this magic trick, the table cloth that is pulled out from under the plates is the outside force.
Detailed explanation-2: -Newton’s first law says that the tableware will remain motionless unless acted upon by an outside force. To set the objects on the table into motion, the horizontal force acting upon them in this case is the frictional force between them and the table cloth.
Detailed explanation-3: -Plain and simple, the Tablecloth Trick works because of inertia. In his First Law of Motion (there are three), Newton described inertia as the tendency of an object at rest to remain at rest unless a force acts upon the object to move it.
