unit 4 lesson 10 force and motion
newtons third law
in the picture, what are the action and reaction forces?
the book pushes down on the table and the table pushed up on the book
gravity pulls the book down
gravity pulls down and friction pushes up
gravity pushed the book up
In the picture, the action force is the book pushing down on the table, and the reaction force is the table pushing up on the book.
In the given scenario, the action force is the force exerted by the book on the table. The reaction force is the force exerted by the table on the book, pushing it upward.
To determine the action and reaction forces in the given scenario, we need to understand Newton's Third Law of Motion.
Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object simultaneously exerts a force of equal magnitude but in the opposite direction on the first object.
In the given scenario, we have a book and a table. The book pushes down on the table, and in response, the table pushes up on the book. This creates a pair of action and reaction forces.
Therefore, the action force is the book pushing down on the table, and the reaction force is the table pushing up on the book.
