B. femur slides and rolls in opposite directions
C. femur slides and rolls in the same direction
D. femur increases its angle in relation to the pubis

Question 6

What position would produce optimal muscular force generation? (MC)

Answer 6

A. when the muscle is slightly stretched past resting length
B. when the muscle is fully contracted
C. when the muscle is fully lengthened
D. when the muscle is at resting length

Question 7

An ice moving continuously on a flat and smooth surface is an example that best represents which of Newton’s laws? (MC)

Answer 7

A. Newton’s 1st law
B. Newton’s 2nd law
C. Newton’s 3rd law

Question 8

What is the definition of torque? (short answer)

Answer 8

The perpendicular force times the length of the lever arm

Question 9

Explain stress-strain to failure. (short answer)

Answer 9

Stress is the amount of force placed on a tissue, and strain is the amount of give a tissue has in response to stress. A tissue has a certain amount of strain it can withstand before it reaches its breaking point. In a stress-strain curve there is a toe region, where there is not much strain on the tissue. There is an elastic region, where there is stress placed on a tissue and strain, there is no tearing at this point. There is a plastic region, where there is a lot of strain on the tissue, and we start to see microtears. At the end of the plastic region is where the failure point is, and the tissue breaks completely.

Question 10

What is the relationship between force and velocity? (MC)

Answer 10

A. force and velocity are directly proportional
B. force and velocity are inversely proportional
C. force does not effect the velocity of a movement
D. none of the above
