How does friction impact the amount of mechanical energy produced by a machine?
Well friction is the opposing force to any object who is doing work against another. So the force needed to overcome friction costs more energy than required thus decreasing efficiency of the machine.
Reducing friction increases the ideal mechanical advantage of a machine?
Reducing friction helps to minimize energy loss, making the machine more efficient. This allows the machine to transfer more of its input force or energy into useful work, increasing its ideal mechanical advantage.
What describes the relationship between friction and IMA for a simple machine?
Friction reduces the mechanical advantage (IMA) of a simple machine by causing energy losses in the form of heat. As friction increases, the effectiveness of the machine in transmitting force or lift decreases, ultimately lowering the mechanical advantage.
How does reducing friction increase the mechanical efficiency of a machine?
Reducing friction decreases the amount of energy lost as heat during machine operation. This allows more of the input energy to be converted into useful work, improving the mechanical efficiency of the machine. Lower friction also reduces wear and tear on components, leading to less maintenance and longer machine lifespan.
What energy transformation in a washing machine?
In a washing machine, electrical energy is transformed into mechanical energy to rotate the drum and agitate the clothes. This mechanical energy then causes friction and movement of the clothes, resulting in kinetic energy and thermal energy to wash and dry the clothes.

What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
Why does friction reduce the mechanical advantage in machines?
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.
What energy transformation takes place in a washing machine?
Electrical energy is changed into mechanical energy
Friction causes mechanical energy to be transformed into what?
Friction causes mechanical energy to be transformed into heat energy.
How does mechanical advantage differ from ideal mechanical advantage?
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
How does friction change a machines mechanical advantage?
Friction reduces the efficiency of a machine by converting some mechanical energy into heat. This means that the output force of a machine can be lower than expected due to frictional losses, which can reduce its mechanical advantage. In other words, friction can make it more difficult for a machine to perform work by increasing the force needed to overcome resistance.
What is example of mechanical energy changes to heat energy?
Friction, for example the heating in brake discs and pads when slowing a vehicle
