The book pushes down on the table and the table pushes up on the book.
The book pushes down on the table and the table pushes up on the book.
Gravity pushes the book up.
Gravity pushes the book up.
Gravity pulls the book down.
Gravity pulls the book down.
Gravity pulls down and friction pushes up.
The correct answer is:
The book pushes down on the table and the table pushes up on the book.
In the given picture, the action and reaction forces can be described as follows:
1. The book pushes down on the table: This is the action force exerted by the book onto the table.
2. The table pushes up on the book: This is the reaction force exerted by the table onto the book in response to the action force.
Therefore, the correct answer is:
The book pushes down on the table and the table pushes up on the book.
To identify the action and reaction forces in the given scenario, we need to understand Newton's third law of motion. According to this law, every action has an equal and opposite reaction.
In this case, the action force is the weight or force of gravity acting on the book. Gravity pulls the book downwards towards the table. The reaction force to this action is the normal force exerted by the table on the book, which pushes the book upwards.
So, the correct answer would be: "The book pushes down on the table, and the table pushes up on the book."
