Why would it require greater force to start a refrigerator moving than to start a book moving?

the force (F) to move is the coefficient of friction(u) times the normal force, or weight(W). F = uWSince the weight of the fridge is much more than the book it takes more force to move it

Why is a greater force needed to move a refrigerator than it's needed to move a book?
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.
Which of the following does not require work to be done An increase in?
"Work" is the product of force times distance; so if you apply a force without moving, or if you have a movement without a force, then there is no work involved.
How does unbalanced forces affect an object?
Consider an object in empty space. There are two forces pushing from opposite sides, one force (force A) on the left pushing with 2 newtons of force, the other (force B) on the right pushing with 1 newton. Since force A is pushing with a greater force than force B, the result will be the object moving right. The object is also moving with a force of 1 newton, because force A is 1 newton greater than force B.
Is the force which prevents the wagon from moving greater than equal to or less than the pull of the engine?
Air friction and rolling resistance
Do surfaces touch more when there is less force or greater force?
Greater force
Why is a greater force needed to move a refrigerator than it's needed to move a book?
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.
Infer the net force on a refrigerator if you push on the refrigerator and it doesnt move?
If an object is not moving, then the net forces working on it are zero. If there were a non-zero net force, the refrigerator would move in the direction the force was applied.
How do objects start moving?
Objects start out as either a rest or moving. If they are at rest, they require a force to be applied for them to start moving. If they are moving, they require a force to either slow them down or to make them stop. That means that once something starts moving, it will move forever, unless a force slows it down. The catch is that the force can be friction.
Do multi-stage rockets require more force to keep the rocket moving?
no they do not
What is the friction that hinders a stationary object from moving on a surface when a force is applied to that object?
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
What is motion stopped and started by?
Force. The stronger the force opposing the motion, the quicker the moving object will stop. The stoping force is usually supplied by a braking system of some sort. The force of brake calipers on a car's brake discs , is very very powerful . To start motion you still need Force. The greater the force the greater the acceleration. The force of a moving object is usually supplied by power from an Engine of so me kind
What is the difference from a moving car and a stationary car?
speed! a moving car is having a force greater than the friction of the tires/air (and gravity on a steep upward hill) applied to it, and is moving forward. The force can come from the engine, or external forces.

Is the force needed to accelerate a car greater than the force needed to accelerate a bicycle to the same velocity?
Force is directly proportional to mass. Therefore, even both the car and bicycle are being accelerated to the same velocity, accelerating a car would require more force since it has a greater mass.
If 2 objects are moving around tree 1 at radius on 10m and other at 20m which oject has facing more cetrifugal force?
he body which is moving along the radius of 10m experiences greater centrifugal force as it is inversely proportional to its radius
Infer the net force on a refrigerator if you push on the refrigerator and it dosen't move?
zero
