Answer 1

Joints

Question 2

What is the function of a lever?

Answer 2

To increase the speed at which a body part can move

Question 3

What are the 3 parts of a lever system and how are each of them represented?

Answer 3

The fulcrum( a triangle)
The load (a square/rectangle)
The effort ( an arrow pointing in the way the effort in moving)

Question 4

In a lever system diagram what does the straight line represent?

Answer 4

The lever arm

Question 5

What is the fulcrum?

Answer 5

The point of movement generally at the centre of a joint

Question 6

What is the load?

Answer 6

This is the body’s weight or an external object eg a dumbel that moves as a result of the effort on the lever

Question 7

What is the effort?

Answer 7

A muscular force that moved the load

Question 8

Is a first class lever mechanical advantage or disadvantage?

Answer 8

Mechanical advantage

Question 9

Describe the lever system if a 1st class lever

Answer 9

Fulcrum is bellow the lever arm and in the middle, the load is on the left and the effort is on the right pointing down

Question 10

Is a second class lever mechanical advantage or disadvantage?

Answer 10

Mechanical advantage

Question 11

Describe the lever system of a second class lever

Answer 11

Fulcrum is below the lever arm and on the right, the load is in the middle and the effort is on the left pointing up

Question 12

Is a 3rd class lever mechanical advantage or disadvantage?

Answer 12

Mechanical disadvantage

Question 13

Describe the lever system of a 3rd class lever

Answer 13

The fulcrum is on the left and below the lever arm, the effort is in the middle and pointing up and the load is on the right

Question 14

Give a sporting example of a first class lever

Answer 14

When the head and neck are extended and fixed eg when heading a football

Answer 20

The bone

Question 21

What is mechanical advantage?

Answer 21

Being able to move large load with a smaller effort

Question 22

What is mechanical disadvantage

Answer 22

When a lever’s load arm is longer than its effort arm

Question 23

Answer 23

Sagitall
Frontal
Transverse

Question 24

What is the Sagitall plane of movement?

Answer 24

The plane of movement that Divides the body left to right

Question 25

What is the Frontal plane of movement?

Answer 25

The plane of movement that divided the body front and back

Question 26
