Friction. It can be reduced by lubricating substances such as oil.
Lubricating a machine reduces friction between its moving parts, allowing them to move more freely and smoothly. This can result in improved efficiency and reduced wear and tear on the machine, ultimately leading to increased output work by maintaining optimal functioning of the machine.
Friction between the parts of an engine is reduced by applying oil between its parts. mobiloil is particularly used for this purpose.

Reducing friction on a machine can lead to smoother operation, less wear and tear on moving parts, and reduced energy consumption. However, it can also reduce the stability or control of the machine in some cases.
The type of friction that exists between a surface and moving air is called air resistance or drag. This friction force opposes the motion of the object through the air and increases as the speed of the object increases. It is influenced by factors such as the shape and surface area of the object, as well as the speed at which it is moving.
Static friction exists between two surfaces that are not moving past each other. This type of friction prevents the surfaces from moving when a force is applied.
Gravitational force between two objects can be reduced by increasing the distance between them. This can be achieved by moving the objects farther apart from each other. The gravitational force decreases with the square of the distance between the objects.
No,because it has moving parts in it and a simple machine dose not have any moving parts
Electricity is the movement of electrons between atoms. Magnetism only exists around moving electrons.
Friction can be harmful to a machine because it can cause wear and tear on moving parts, leading to increased maintenance and repair costs. Excessive friction can also lead to overheating, reduced efficiency, and potentially even system failure.
