Answer 7

it runs from the left to right (across the body)

Question 8

frontal plane

Answer 8

splits the body into front and back

Question 9

Answer 9

runs from head to toe

Question 10

Answer 10

frontal plane + sagittal axis

Question 11

what axis and plane does a front somersault/forward roll/running action take place on

Answer 11

sagittal plane + transverse axis

Question 12

what axis and plane does a 360° twist (ice skating spin)/discus thrower rotating in circle take place on

Answer 12

Question 13

what is in the middle in a first class lever

Answer 13

fulcrum

Question 14

what is in the middle in a second class lever

Answer 14

load (resistance)

Question 15

what is in the middle in a third class lever

Answer 15

effort

Question 16

example of a first class lever

Answer 16

tricep

Question 17

example of a second class lever

Answer 17

gastronemius

Question 18

example a third class lever

Answer 18

bicep

Question 19

formula for mechanical advantage

Answer 19

mechanical advantage = effort arm / resistance arm

Question 20

what is the effort arm

Answer 20

distance between the fulcrum and the effort

Question 21

what is the resistance arm

Answer 21

distance between the fulcrum and the load

Question 22

what is mechanical advantage

Answer 22

if a lever’s effort arm is longer than its load arm, it is said to have high mechanical advantage. Levers with high mechanical advantage can move large loads with a relatively small amount of effort. Second class levers always have high mechanical advantage
