True. Friction causes resistance within a machine, leading to loss of energy in the form of heat. This decrease in efficiency can result in the machine requiring more energy input to overcome friction and perform its intended task.
False. Friction typically reduces the efficiency of a machine by converting some of the input energy into heat, rather than converting it into mechanical energy.
False. Friction can significantly affect the efficiency of a machine by causing energy losses and reducing its overall performance. Minimizing friction through proper lubrication and design can help improve the efficiency of a machine.
the answer is false whoever answered before was trolling
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.

False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
False. Air resistance is friction. A meteor coming in from space hits our atmosphere and glows brightly due to the airs friction.
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
