What is the work output of a machine never equal to the work input?
It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
Does an ideal machine have an effciency of 100 percent?
No, there is not such thing as an ideal machine; it's just an idea.
Is work input always equal to work output?
Yes the only thing a machine changes is force,distance or direction
What causes the output work of a machine to be less than the input force?
Some of input energy is wasted in heating up the molecules, sound,etc therefore the resultent output work is always less than the input force due to loss of energy.
What is the work output of a machine never equal to the work input?
It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
Why in a real machine is the output work always less than the input work?
That's related to the fact that in real machines, some energy is wasted.
Why in a real machine the output work is always less the input work?
In a real machine, part of the energy (or power) is always wasted.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
Does an ideal machine have an effciency of 100 percent?
No, there is not such thing as an ideal machine; it's just an idea.
Is it easier to lift a 50 kilogram box straight up 8 meters or slide it up an inclined plane that is 20 meters long?
While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
Is work input always equal to work output?
Yes the only thing a machine changes is force,distance or direction
How much work is done with 200N of force in unsuccessful effort?
Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance.

What is overcoming adversity?
Overcoming adversity means getting past something that poses an obstacle to your goal. Some adversities people have to work to overcome are poverty, learning disabilities, and racial discrimination.
