The formula for force is Force= Mass x Acceleration. Therefore, you have to use a greater force to move the refrigerator because it has a greater mass than the book.
It would require greater force to start a refrigerator moving than a book because the refrigerator has more mass and therefore more inertia to overcome. Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass, the greater the inertia and thus the greater the force needed to overcome it.
A book sliding off a table is an example of an object experiencing an unbalanced force. The force of gravity pulling the book downward is greater than the frictional force between the book and the table, causing it to accelerate in the direction of the force.
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.
A schoolbag has more inertia than a book because inertia is proportional to mass, and a schoolbag typically has a greater mass than a book. This means that a schoolbag would require more force to move or stop compared to a book due to its greater inertia.
Factors that might affect the force needed to drag a book include the book's weight, the coefficient of friction between the book and the surface it's being dragged on, the angle at which the book is being dragged, and any obstacles or surface irregularities that could increase resistance.

More force is needed to slide a large book across a table than to slide a small book primarily due to the difference in weight and surface area. A larger book typically has a greater mass, resulting in a higher gravitational force acting on it, which increases the friction between the book and the table. Additionally, the larger contact area can contribute to increased friction, requiring more force to overcome it and initiate movement.

This site is not the place to go for answers to your homework or tests. Nobody here is cruel enough to do that to you. It takes less force to lift things on the moon than to lift them on Earth, but the same force to throw them horizontally in both places. You can find the reasons explained in the book and other materials you used in the same class where the questions came from. (Both parts 'A' and 'B'.)
The force needed can be calculated using the equation F = ma, where F is the force, m is the mass (2 kg), and a is the acceleration. Given that the book starts from rest and reaches a speed of 6 m/s in one second, the acceleration is 6 m/s^2. Therefore, the force needed would be 12 N.
Greater the gravitational force it exerts on another object.
