What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
Why does reducing the friction of a machine increase it's efficiency?
Reducing friction in a machine decreases the amount of energy lost as heat, making the machine more efficient. This means that more of the input energy is converted into useful work or output, increasing the overall 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.
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 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.

What increases the work output of a simple machine?
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
What role does friction have in reducing mechanical efficiency?
Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.
What does reducing friction in a machine do?
Reducing friction in a machine can help improve its efficiency by decreasing energy wasted as heat. This can lead to lower maintenance costs, lower energy consumption, and increased overall performance of the machine.
What is true about the mechanical advantage of a machine a it increases with greater friction b it decreases as the input distance increases c it is less than the idle mechanical advantage?
c) It is less than the idle mechanical advantage. The actual mechanical advantage of a machine is always less than the ideal mechanical advantage due to factors like friction and energy losses in the system.
Why it is important for you to reduce friction on compound machine?
Reducing friction on a compound machine is important because it helps improve the efficiency of the machine by minimizing the energy lost due to friction. Lower friction also translates to less wear and tear on the machine's components, ultimately extending its lifespan and reducing maintenance needs. Additionally, decreased friction can enhance the overall performance and precision of the machine's operations.
How lubericating a machine affects the output force exerted by the machine?
It maximizes it, by reducing the internal losses to friction.
How does the output work done by machine change when friction is reduced?
Increases
