PLEASE HELP!!!!!!!

Answering the following questions will help you to focus on the outcomes of these experiments:

How does the length to height ratio (the IMA) of trial 1 compare to trial 2?
Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?
If a machine was 100% efficient, how would the AMA compare to the IMA?
Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)
Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.


Question 1: After completing this experiment, was your hypothesis supported? Explain why or why not.

^Experiment^ In this experiment, you will determine the IMA, AMA, and efficiency for the simple machine, the inclined plane.

The materials for this experiment are:

a smooth board
smooth block or other object to drag up a plane
a spring scale (calibrated in newtons)
string
books or blocks to support the inclined plane
and a meter stick.

Your job is to observe the experiment and collect your own data from this demonstration. Be ready to record your observations and data.

You will be pulling an object up an inclined plane at different inclines.
Make and record a hypothesis about how changine the slope of inclined plane will affect the efficiency.
Measure the height and length of the plane, record the measurements.
Measure the mass of the object, and record.
Convert the mass from grams to newtons by dividing by 102, and record.

Now slowly and steadily pull the object up the incline with the spring scale and string kept parallel to the incline.
Record the readout on the scale. This will be the effort force.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.

Question 2: How does the length to height ratio (the IMA) of trial 1 compare to trial 2?
Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?
If a machine was 100% efficient, how would the AMA compare to the IMA?
