The Fascinating World of Physics

What law of physics explains why a magician can pull a tablecloth out from under dishes and glasses on a table without disturbing them?

A. Law of Gravity

B. Law of Inertia

C. Law of Thermodynamics

The Law of Inertia

The law of inertia, also known as Newton's first law of motion, explains how objects tend to stay in their state of motion unless acted upon by an external force. This is why when a magician rapidly pulls a tablecloth, the dishes and glasses on top have a tendency to remain at rest due to their inertia.

Physics is a fascinating field that helps us understand the fundamental principles governing the behavior of the universe. One of the most intriguing concepts in physics is the law of inertia, which plays a significant role in various everyday phenomena.

When a magician performs the trick of pulling a tablecloth out from under dishes and glasses on a table without disturbing them, they are actually utilizing the principle of inertia. The objects on the table, due to their mass and state of rest, tend to remain in that state unless acted upon by an external force.

Newton's first law of motion states that an object will stay at rest or continue to move in a straight line at a constant speed unless acted upon by a net external force. In the case of the magician's trick, the rapid movement of the tablecloth imparts little force on the objects, allowing them to maintain their state of rest due to inertia.

So next time you witness a magician performing this seemingly impossible feat, remember that it's not magic but rather the fascinating laws of physics at work!
