I haven't gotten around to repeating it yet. I've been so busy,

had so much homework, the dog ate it, etc.

How does actual mechanical advantage compare with ideal mechanical advantage?

The actual mechanical advantage is usually less, due to losses.


What two quantities does mechanical advantage compare?

Input and output (of energy)


How does the ideal compare with the actual mechanical advantage?

The ideal mechanical advantage is based on the geometric relationships of a machine's components and assumes no energy losses, while the actual mechanical advantage accounts for friction, inefficiencies, and other factors that can reduce the output compared to the input force. In reality, the actual mechanical advantage is always less than the ideal mechanical advantage due to these energy losses.


How you would measure the mechanical advantage of a bicycle?

To measure the mechanical advantage of a bicycle, you would compare the input force applied by the rider to the output force produced at the wheels. The mechanical advantage is calculated by dividing the output force by the input force. In the case of a bicycle, the mechanical advantage helps determine how efficiently the rider's pedaling translates into forward motion.


If a machine was 100 percent efficient how would the AMA compare to the IMA?

If a machine was 100 percent efficient, the AMA would be equal to the IMA. This is because in an ideal scenario where the machine loses no energy to friction or other factors, the AMA (actual mechanical advantage) would be the same as the IMA (ideal mechanical advantage).


How does your actual mechanical advantage compare to this theoretical mechanical advantage for each of the trials?

The actual mechanical advantage is the measured force output divided by the measured force input, while the theoretical mechanical advantage is calculated based on the quotient of the load distance and effort distance. Comparing the two allows us to evaluate the efficiency and effectiveness of the machine in translating input force into output force. Discrepancies between the actual and theoretical mechanical advantages signify losses due to factors like friction, inertia, or other inefficiencies in the system.


Distinguish between theoretical mechanical advantage and actual mechanical advantage How will these compare if a machine is 100 percent efficient?

Theoretical mechanical advantage is the ratio of the input force to the output force without considering friction, while actual mechanical advantage includes frictional losses in the machine. If a machine is 100 percent efficient, there will be no frictional losses, so the theoretical and actual mechanical advantages will be the same, resulting in a 1:1 ratio of input force to output force.


How can you compare and contrast an experiment?

You have to have either done two experiments or read two experiments or read one experiment and do the other in order to compare and contrast an experiment.


How can we compare and contrast work mechanical advantage and efficiency?

Mechanical advantage measures the ratio of output force to input force, showing how much a machine amplifies force. Efficiency, on the other hand, measures how well a machine uses energy and is the ratio of output work to input work. A high mechanical advantage means a machine can achieve a large force output, while high efficiency means a machine minimizes wasted energy during its operation.


An experiment that you can compare your test results?

How is a control useful in a scientific experiment?

A control experiment provides a benchmark against which to compare the results of the main experiment. For example, to know if heating a material changes its resistance, you must be able to compare the results of the heated experiment to a copy in which the material was left unheated.
