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 won't a book resting on a table fall to the ground?
Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.
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.
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.
A book weighing 29 N is placed on a table How much support force does a table exert on the book?
29 Newtons
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.
Think Critically A book sliding across a table slows down and comes to a stop Explain whether the forces acting acting on the book are balanced or unbalanced.?
The forces are unbalanced. The force of Friction is obviously greater than whatever force is pushing the book in the direction of travel, if one is pushing it at all. If the forces on the book were balanced, the book would continue to slide with a constant velocity.
Does a book sliding on a table violate newtons first law of motion?
No. If the book is sliding along the table, then there must be some external force being applied to the book to cause the movement. You pushed the book and created a force to move. And this is exactly what the first law is saying- a body at rest (net forces acting on book=0) remains at rest unless acted upon my some external force.
Why is more force needed to slide a larger book across a table than to slide a small book across the same table?
Gravity - and friction. The larger book has more gravity - holding it own onto the desk. Friction stops the book sliding sideways.
When a book stops sliding on a table top it is because of?
friction
Is force of friction correlated to force of gravity?
It depends. Two surfaces which are pressed together will show a frictional force resisting any sliding. If they are pressed together by gravity (e.g. such as for a book lying on a table), then the frictional force resisting a horizontal push will depend on the weight of the book, which depends on the force of gravity.
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.
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.
Is a textbook on a table a balanced force or an unbalanced force?
A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.
When you put a book on a table the table pushes on the book?
I think the answer is that the table is pulling down on the book.
Why won't a book resting on the table fall to the ground?
Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.
