Does the book on the table have a force acting on it going upwards if no why or yes?

For example, if the book is resting on a table, gravity pulls the book down, and the table pushes the book up.

Yes, the book on the table does have a force acting up on it.
At rest (the book is not moving), the book actually has two forces acting on it:
1: weight/force of gravity -- pulling down on the book (keeping it on the table)
2: normal force -- the force of the table pushing back up on the book
*Note: force of gravity = normal force
I hope that helps :)

∙ 12y agoIt depends on the angle that you push with. There is no friction involved if you push straight down at a 90 degree angle. Any other angle will involve friction which, if exceeded, will cause the book to move.

When a cat sleep on a table the net force on it is?
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.

Would a book falling off a table be a balanced force?
The force of gravity causes a book to fall, but someone has to push it to the edge of the desk, or off the desk so that the force of gravity is greater than the normal force acting on the book.

Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.
What two forces act on the paper cup as the repeling magnets contend to keep it in this position?
Gravitational force (gravity) acting downwards and the normal force of the table acting on the cup upwards. These two forces when added together equal zero. Therefore, there is no movement. They keep that cup and its contents in position.
Is it possible for an object not to be in motion and still have forces acting on it Explain?
Yes. An object will remain at the same velocity including zero velocity (not in motion) if the forces on it are balanced. There may still be forces on it but if they cancel out it will not change its velocity. For example a brick sitting on a table on the planet Earth. The force of gravity is acting on the brick. If the table was not there the brick would accelerate downwards (fall) but because the table is there and is exerting an upwards force which exactly matches the gravitational force the brick remains stationary. (At least in the frame of reference of the brick/table/floor/Earth, if you were observing it from the moon it would be moving and accelerating rather quickly but that is probably beyond the scope of this question.......)
Why wont a book resting on the table fall to the ground?
Apply Newton's third law of Universal Dynamics. 'To every force there is an equal and opposite force'. The book is applying a downward force., so the table is applying a resistant force upwards, which are equal forces , so the book does not fall.
What is support force?
Support force refers to the upward force exerted by a surface to counteract the downward force of an object resting on it. It prevents the object from falling through the surface due to gravity. Support force can also be known as normal force.
As long as an object at rest is there a force acting against it?
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
Which of these would you include in a free body diagram of a coin balanced on its edge on a table?
The force of gravity acting on the coin.
Why does an object on a table not crash to the ground?
The object has weight - that is, gravity is pulling it down.However, the table is in the way, and it gets "squashed" by the object's weight, so it exerts a "normal reaction force" upwards on the object.The downward weight and upward reaction force cancel out, so the book stays still on the table.
If a book is placed on top of the table are there forces acting on the book?
Yes. For a start, gravity pulls it down. Also, the table pushes up on the book, thus canceling the force of gravity.
Is gravity the force applied up or down on an object?
Gravity pulls things downwards, so it is pointed downwards. If an object is resting on something (like a book resting on a table) an equal force will point upwards and that force is known as the normal force.
What is the net force equation?
It means the same as the sum of all the forces acting on an object. Note that since forces are vectors, they have to be added as such. For example, an book resting on a table has gravity pulling it down; on the other hand, the table is pushing the book upwards (by Newton's Third Law; since the book pushes down on the table). Adding all the forces together, you get a zero force - which must be so, for the object to remain at rest.
