When a book is pushed across a table surface, which type of friction mainly opposes its motion?
Sliding friction
Friction is the force that opposes the relative motion between two surfaces in contact.
When a book slides flat over a table, its surface moves directly against the table surface without rolling, so the resisting force is sliding (kinetic) friction.
Rolling friction applies to bodies like wheels or balls that roll, fluid friction (drag) acts on objects moving through a liquid or gas, and magnetic friction is not the force involved here.
Hence, the friction that mainly opposes the book's motion is sliding friction.
The range of ______ force is of the order of 10 −16 m .
Force of attraction between molecules of the same substance is called_____.
All the non-zero vectors are called ______.
