When shoveling dirt, the output work is _____.
A.the force you exert on the shovel times the output distance
B.greater than the input work if you exert more force
C.the force exerted by the shovel on the dirt times the output distance
D.the force exerted by the shovel on the dirt minus the output distance
i think it is B
This is late but it is
C.) the force exerted by the shovel on the dirt times the output distance.
the output work is the actual work done on the dirt
this is less than the input work due to frictional and other losses
so what is it
The output force times the output distance is called the output work.
When you use a machine, the amount of output work can never be greater than the amount of input work.
Your answer is c.)the force exerted by the shovel on the dirt times the output distance.
Well, let me shovel some humor your way. The correct answer is actually C. The output work is determined by the force exerted by the shovel on the dirt, multiplied by the distance over which the dirt is moved. So, while exerting more force might make you feel like a superhero, it doesn't necessarily mean the output work will be greater. Keep shoveling and stay grounded!
To determine the correct answer, let's break down the concept of work and analyze how it applies to shoveling dirt.
Work, in terms of physics, is defined as the transfer of energy that occurs when a force is applied to move an object over a distance. It is calculated by multiplying the force exerted on an object by the distance over which the force is applied.
Now, in the context of shoveling dirt, let's consider the different components involved. When you shovel dirt, you exert a force on the shovel handle. This force is responsible for moving the shovel and the dirt. The output distance refers to the distance the dirt is moved when you shovel it.
Based on this understanding, the correct answer to the question "When shoveling dirt, the output work is _____" is A: the force you exert on the shovel times the output distance.
Option B states that the output work is greater than the input work if you exert more force. However, the input work is not mentioned in the question, so we cannot make any comparisons between the two.
Option C describes the force exerted by the shovel on the dirt times the output distance. This is incorrect because the force exerted by the shovel on the dirt is not the same as the force you exert on the shovel. The shovel is simply a tool that helps you apply your force to the dirt.
Option D states that the output work is the force exerted by the shovel on the dirt minus the output distance. However, this equation is not correct as the work is calculated by multiplying the force and the distance, not by subtracting them.
Therefore, the correct answer is A - the force you exert on the shovel times the output distance.
