Because friction causes a dissipation of heat energy and other kinetic energy. If you use the equation f = ma (Newton's law), where f= force, m= mass; a= acceleration, you can apply this to any machine and factor friction into the mass x acceleration equation. it will always decrease hypothetical force when applied with friction.

What force stops machines from being 100 percent efficient?
One major factor that limits the efficiency of machines is friction. Friction creates resistance as moving parts come into contact with each other, leading to energy losses in the form of heat. Additionally, other factors such as air resistance, electrical resistance, and imperfections in materials can also contribute to reducing the overall efficiency of machines.
What is the force that prevents all machines from being 100 percent efficient?
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
What force stops manchines from being 100 percent efficient?
Reducing its temp. heat is the most common form of energy, and when a machine has friction, it is creating heat. by reducing the amount of friction, maybe by using some kind of lubricant between the objects, it will create less heat and thus use less energy input, with a higher input to out put ratio.
What kind what prevents a machine to be 100 percent efficient?
Friction between moving parts, energy losses due to heat, and limitations in material strength are factors that prevent a machine from being 100% efficient. These inefficiencies result in some of the input energy being wasted rather than being fully converted into useful work.
What kinds of machines produce heat when being used?
Some examples of machines that produce heat when being used include ovens, stoves, heaters, furnaces, computers, and automobiles. These machines generate heat as a byproduct of their operation due to friction, electrical resistance, or combustion processes.
Why is no machine 100 percent eficent?
No machine can be 100% efficient due to factors such as friction, heat loss, and external factors that affect performance. These limitations result in energy being lost or wasted during the operation of the machine, reducing its overall efficiency.
Why are supermarkets allowed to replace people with machines?
People are being replaced by machines because machines are faster, more efficient, and most importantly they do not fatigue or have to be payed (except for when they are bought) , the supermarkets and factories realize this so the boards of the companies allow it.
What common household appliances use friction?
Some common household appliances that use friction include vacuum cleaners (friction between the rotating brush and the floor), blenders (friction between the blades and the contents being blended), and washing machines (friction between the clothes and the agitator or drum).
Which are the best quality and most affordable washing machines?
There are many types of washing machines being sold around the world. The Samsung j1043 is a great machine and is efficient and is fairly priced at under 1000 US dollars.
How do machines make your lives easier?
machines make life easier by being more efficient than us humans. we have so much on our minds and easily get distracted but machines are machines, so they work at a steady constant rate. if this answer didnt help you (sorry!) , but you can reword your question and im sure a better answer will come up! :)

Why is a machine is never 100 efficient?
A machine can never be 100% efficient because some energy is always lost as heat due to friction, air resistance, and other factors. These losses result in the machine not being able to convert all input energy into useful output energy.
