Because of friction
Friction between the book and the floor creates resistance to its motion, making it difficult to push. The weight of the book also plays a role in increasing the force required to move it. Additionally, irregularities or imperfections on the floor's surface can further impede the book's movement.
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.
For example, if the book is resting on a table, gravity pulls the book down, and the table pushes the book up.
An example of unbalanced force causing a change in motion is when a person pushes a book across a table. The force exerted by the person is greater than the force of friction between the book and the table, causing the book to accelerate in the direction of the push.
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.
An example of force and motion is when you push a book across a table. Your hand exerts a force on the book, causing it to move. The book will continue to move until another force, like friction, acts on it to stop its motion.
I will push the book
Push him off
A cat can push a bottle back on the table by using its paws to nudge or bat at the bottle until it moves back into place.
Well i Got This Great Book"Push" In Barnes&Nobles It Cost 13.00 Its Worth It. Its The Best Book (: Hope You Enjoy It
I had to push back the chair when rising from the table.I was asked to push in the chair to make more room round the table.
A book placed on a table doesn't move because it is in a state of static equilibrium, where the forces acting on it are balanced. The force of gravity pulling the book downward is countered by the normal force exerted by the table pushing upward. Without any external force applied to it, such as a push or pull, the book remains at rest due to Newton's first law of motion, which states that an object at rest will stay at rest unless acted upon by an unbalanced force.
