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.
What else can I help you with?
What type of friction holds a penny on surface of book when lift cover?
static friction, friction between two non-moving objects.
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 would be used to cause a book to slow down and stop when pushed?
The type of friction that would cause a book to slow down and stop when pushed is kinetic friction. As the book moves across a surface, the frictional force between the book and the surface opposes the motion, eventually stopping the book altogether.
When a book is pushed across a table how many forces are acting on it?
When a book is pushed across a table, there are two forces acting on it: the force applied by the person pushing the book (force of push) and the force of friction acting in the opposite direction on the book due to contact with the table surface.
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?
Yes, if a book is stationary on a table, the forces acting on it are in equilibrium. The resultant force acting on the book would be zero, as the forces are balanced and there is no net force causing any acceleration or movement.
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?
The force of friction would also be 1 N, equal in magnitude but opposite in direction to the force you are pushing with. This equal and opposite force of friction is what allows the book to move at a constant velocity.
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.
If a student pushes a book across the table with a force of 6 n and the force of friction is 4 n what is the net force on the book?
The net force on the book is calculated by subtracting the force of friction from the force applied by the student. In this case, the net force is 2 N (6 N - 4 N).
Which force slows a book sliding on a table?
The force that slows down a book sliding on a table is mainly friction. As the book moves across the table, the friction between the book and the table surface opposes the motion, causing the book to slow down until it eventually stops.
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.
What are thre forces acting on the book?
The three forces acting on a book could include gravity, which pulls the book downward towards the Earth; the normal force exerted by the surface the book is resting on, which pushes the book upwards to balance gravity; and friction if the book is being pushed or pulled across a surface.
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.
When you push with a horizontal 10-N force on a book that remains at rest what is the force friction?
The force of friction acting on the book will be equal in magnitude but opposite in direction to the applied force, so it will also be 10 N. This is necessary to keep the book at rest as there is no net force acting on it.
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.
