Write a Description of the reaction force
A book is pushed down on a table with a force of 25N.
Ah, the reaction force! It's like the unexpected guest at a party. When you push a book down on a table with a force of 25N, the table doesn't just stand there like a statue. Oh no! It springs into action, pushing back against the book with an equal force known as the reaction force. It's like a wrestling match between the book and the table, with both of them giving it their all. So remember, when you push something, expect the reaction force to push right back, just like a party crasher who can't resist joining in on the fun!
When a book is pushed down on a table with a force of 25N, the table exerts an equal and opposite force on the book. This is known as the reaction force. The reaction force occurs because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the action is the book pushing down on the table, and the reaction is the table pushing up on the book with a force of 25N. This reaction force allows the book to remain in equilibrium and prevents it from sinking through the table.
The reaction force, also known as the normal force, is a force that acts perpendicular to the surface of an object in contact with another object. In this case, the book is pushed down onto a table with a force of 25N. To understand the reaction force, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the book is pushed down onto the table with a force of 25N, the table exerts an upward force on the book with the same magnitude but in the opposite direction. This force is called the reaction force or the normal force.
To calculate the reaction force in this case, we need to consider that the weight of an object is equal to its mass multiplied by the acceleration due to gravity (approximated to 9.8 m/s² on Earth). So, if we know the mass of the book, we can calculate its weight. The reaction force exerted by the table will be equal to the weight of the book.
Therefore, to get the answer, we need to determine the mass of the book and multiply it by the acceleration due to gravity (9.8 m/s²) to find the weight of the book. The weight of the book will then be equal to the reaction force exerted by the table.
