If a book is pushed by 10N and the friction is 8N what is the resultant force?

In fact, there is an infinite number of answers because force is a vector, meaning that it has a magnitude and an orientation. For example, if someone pushes horizontaly onto the book (10N) and the friction is 8N in the opposite direction, the resultant force is 2N. But if the book is pushed at an angle, the resultant force changes.

A book of mass 10kg rests on a holizontal table. What is the resultant of action and reaction forces if the book is stationery?
My, that is a fairly heavy book! Earth attracts the book with a force of 98 Newtons. Therefore, the book will also attract Earth with the same force. For the book to be in equilibrium, the table has to push the book up with a force of 98 Newtons. Therefore, the book also pushes down on the table, with a force of 98 Newtons.
What forces are acting on a book that is lying on a table?
Gravitational force (weight), pointing down.Reaction force, equal to the gravitational force (weight), exerted by the tabletop, pointing up.
Is it possible for a book moving at a constant speed to have a change in velocity?
Yes, if an unbalanced force acts on the book, such as friction, which will slow the book down and eventually cause it to stop.
What do you use to measure frictional force?
The maximum frictional force acting on an object is found by the equation F = Fn * Fs, where Fn is the normal force acting on the object (by Newton's 3rd Law, Fn can equal the body's weight in magnitude) and Fs is the static friction property of the surface, usually determined by experiment or given. If the body is already in motion, F = Fn * Fk, where Fk is the kinetic friction. This is also a property of the surface determined by experiment. It is usually significantly less than the static friction. (This is why it is easier to push a heavy crate across the floor once you start to move it.) Example: The static friction of a desk is determined by experiment to be .5. What is the required horizontal force to be applied to a 10 N book in order to move it? 1) To move the book, the applied force must exceed the maximum frictional force acting on it. so Fapp > F. 2) Find F. F = Fn * Fs. F = (W of book)(.5) as Fs is given to be .5. By Newton's third law, the weight of the book equals the normal force on it from the desk. F = (10 * .5) The frictional force = 5 N. Therefore, you must apply a force greater than 5 N horizontally.
What type of friction holds a penny on surface of book when lift cover?
static friction, friction between two non-moving objects.
What type of friction would be used to cause a book to slow down and stop when pushed?
Sliding friction causes a book to slow down and stop when pushed. ------- Might also be known as dynamic friction.
When you push a book why does it stop?
When you push a book, it stops because of the force you are applying to it. The friction between the book and the surface it is resting on counteracts the force you are applying, bringing the book to a stop.
What is Friction Force?
YES, YEA it is Yes it is a force. If not then we would be slipping around. What i have heard is that friction causes a pull in some ways. Say you slid a pencil on the floor with nothing in it's path. Now if you know what inetia (not a force) then you would know that the pencil would stop because of a outside force. And that force is friction. Friction had reduced the pencils speed when it rubbed together on the floor. Now if the pencil was givin more force when you pushed it and the floor was more slik then the pencil would have traveled alot more. This is because the force of friction is a less amount when one surface is smoother. I know this is a horrible explanation but this is what helps me think of the forces. And this is going to prove to my teacher that friction is a force and that inertia is not.
Which force slows a book sliding on a table?
Friction.
If a book remains stationary on a table are the forces acting upon the book in equilibrium what is the resultant of the force acting upon the book?
All of the forces together balance out. The resultant of the forces is therefore nil. That applies to all equilibrium.
If you push horizontally on your book with a force of 1 N to make the book slide at constant velocity how much is the force of friction on the book?
No
Is sliding friction the force that slows a book sliding on a table?
Yes, Sliding friction opposes the movement of the book, slowing it down.
What type of force holds a book on a sloped desk?
Friction.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
Why will a book pushed against the wall not fall?
The book is held in place by the force you are putting against it. Remove your hand (remove the force) and the book will fall due to gravity.
Is friction a contact or non contact force?
friction is a contact force
Is friction a push force or a pull force?
Friction is a phenomenon which acts to resist an applied force, both 'pushing' and 'pulling'. It is a force in itself, and may be considered the opposite of slippery. It will change the path of a body in motion.
