Why is a greater force needed to move a refrigerator than it's needed to move a book?
A greater force is needed to move a refrigerator compared to a book because the refrigerator has more mass and therefore more inertia to overcome. Additionally, the larger surface area of the refrigerator creates more friction with the floor, requiring more force to start and maintain its motion.
Why would it require greater force to start a refrigerator moving than to start a book moving?
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.
Infer why the output force exerted by a rake must be less than the input force?
The output force exerted by a rake must be less than the input force due to energy conservation principles. Some of the input force is used to overcome friction and other resistive forces, resulting in a decrease in the output force available for actual work.
When you push on a stationary object and it doesnt move what kind of force is most likely opposing your efforts?
Friction is the force most likely opposing your efforts when you push on a stationary object and it doesn't move. Friction exists between surfaces in contact and resists the motion of objects.
If the force applied to an object doesnt make the object move then no friction has been done is this true?
No, it is not true. Friction can still occur even if the object does not move. The force applied may overcome static friction but not cause the object to move due to other factors like weight or surface roughness.
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.
Infer the net force on a refrigerator if you push on the refrigerator and it dosen't move?
zero
Why is a greater force needed to move a refrigerator than it's needed to move a book?
A greater force is needed to move a refrigerator compared to a book because the refrigerator has more mass and therefore more inertia to overcome. Additionally, the larger surface area of the refrigerator creates more friction with the floor, requiring more force to start and maintain its motion.
What friction force acts between a refrigerator and the floor when the fridge is pushed?
The friction force between the refrigerator and the floor depends on the coefficient of friction between the two surfaces and the force applied to push the fridge. The friction force will act opposite to the direction of motion to prevent the fridge from sliding. It is essential to overcome this friction force to move the refrigerator.
Why would it require greater force to start a refrigerator moving than to start a book moving?
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.
2 Was it a good idea to force Native Americans to move onto reservations?
no because that is an example of racism and rasism doesnt help anyone
A part that does not move in pulley?
if it is a fixed pulley, itself doesnt move. If it is a rotating pulley, its joint probably doesnt move.
Infer why algae contain pigments other then just cholorophyll?
To move about a tree.
How can I move a refrigerator to clean behind it effectively?
To move a refrigerator to clean behind it effectively, start by emptying the contents and unplugging it. Enlist help to carefully slide the refrigerator away from the wall, being mindful of the flooring. Clean the area behind the refrigerator using a vacuum or mop, and then carefully slide the refrigerator back into place.
Infer why the output force exerted by a rake must be less than the input force?
The output force exerted by a rake must be less than the input force due to energy conservation principles. Some of the input force is used to overcome friction and other resistive forces, resulting in a decrease in the output force available for actual work.

Friction is the force most likely opposing your efforts when you push on a stationary object and it doesn't move. Friction exists between surfaces in contact and resists the motion of objects.
How fast are molecules in a refrigerator moving as compared to a freezer?
Molecules in a refrigerator move faster than in a freezer because the temperature in a refrigerator is warmer than in a freezer. The higher temperature in a refrigerator causes molecules to have more kinetic energy and move at a faster pace compared to those in a freezer.
