MEDAL!!! When a book is sitting on a table does the table push up on the book or does it pull the book down?

@Allenismyname

OpenStudy (nothingwasthesame):

think of newtons law so it would

OpenStudy (anonymous):

which law?

OpenStudy (nothingwasthesame):

law of gravity

OpenStudy (anonymous):

I knew this before but I just forgot it :(

OpenStudy (anonymous):

The force of gravity acting on an object due to its mass. An object's weight is directed down, toward the center of the gravitating body; like the earth or moon, for example. Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate

OpenStudy (anonymous):

so it would actually be "it exerts no force on the book at all" right?

OpenStudy (anonymous):

In the situation described the objects are at equilibrium. If a force is applied than one object would be acting on another.

OpenStudy (anonymous):

oh so the table would be pulling the book down! right?

OpenStudy (nothingwasthesame):

ok its newtons third law

OpenStudy (nothingwasthesame):

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

OpenStudy (nothingwasthesame):

i did not say law of gravity

OpenStudy (anonymous):

ok so tell me if this is the correct answer. Gravity pushes the book down on the table and the table pulls down on the book?

OpenStudy (anonymous):

oops I meant the table push up on the book

OpenStudy (anonymous):

?

OpenStudy (anonymous):

both of it table pushes up a book and book pushes down a table Law III of newton : To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.

OpenStudy (anonymous):

i think but not sure

OpenStudy (anonymous):

Thank You:D

OpenStudy (anonymous):

np but i'm not sure

OpenStudy (anonymous):

i may be wrong
