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?

According to your data, was your hypothesis correct?

Summarize the conclusions that you can draw from this experiment.
Use the questions above to guide your ideas.

Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Question 1 answer: make sure you eat healthy foods and excercise atleast once a day.question 2 answer: sometimes bullying . bullying lowers a persons self-esteem sometimes which can make them not care for themselves to much making them feel bad about there body structer. that or they just have a bad body structer and there family/doctor said its unhealthy how they eat.
