Question 10

Systolic Blood Pressure

Answer 10

2.2.9
The force exerted by blood on arterial walls during ventricular contraction

Question 11

Diastolic Blood Pressure

Answer 11

The force exerted by blood on the arterial walls during ventricular relaxation

Question 12

Cell Respiration

Answer 12

Controlled release of energy in the form of adenosine triphosphate (ATP) from organic compounds in cells

Question 13

Force

Answer 13

4.3.1
Force is a push or pull acting upon an object. It’s a vector quantity, meaning it has both magnitude and direction.

Question 14

Speed

Answer 14

4.3.1
Speed is the rate of movement, measured as distance travelled per unit time, and is a scalar quantity.

Question 15

Velocity

Answer 15

4.3.1
Velocity, a vector quantity, is the rate of change of an object’s position, considering its direction.

Question 16

Acceleration

Answer 16

4.3.1
Acceleration is the rate at which an object’s velocity changes, and it’s a vector quantity.

Question 17

Momentum

Answer 17

4.3.1
Momentum, a product of an object’s mass and velocity, is a measure of the quantity of motion an object has.

Question 18

Impulse

Answer 18

4.3.1
Impulse is the change in an object’s momentum, calculated as the product of force and the time over which it’s applied.

Question 19

Displacement

Answer 19

4.3.1
Displacement refers to the change in position of an object in a specific direction, a vector quantity.

Question 20

Centre of mass

Answer 20

4.3.3
For a uniform, symmetrical object, the COM is at the geometric centre.
In humans, however, it varies with body position.

Question 21

Newton’s First Law of Motion

Answer 21

4.3.7
Inertia
An object will not change its motion unless an unbalanced force acts upon it

Question 22

Newton’s Second Law of Motion

Answer 22

4.3.7
F = ma
The force on an object is equal to its mass times its acceleration

Question 23

Newton’s Third Law of Motion

Answer 23

4.3.7
Action & Reaction
When two objects interact, they apply forces to each other of equal magnitude and opposite direction

Question 24

Skill

Answer 24

5.1.1
Consistent production of goal-oriented movements, learned to a specific task

Question 25

Technique

Answer 25

5.1.7
“way of doing”
Way in which a sports skill is performed

Question 26

Response Time

Answer 26

5.2.8
Response Time = Reaction Time + Movement Time

Question 27

Transfer

Answer 27

5.3.5
The influence of learning and/or performance of one skill on the learning and/or performance of another

Question 28

Fatigue

Answer 28

A reversable, exercise induced decline in performance

Question 29

Drag

Answer 29

The force(s) acting to oppose the motion of an object through a fluid medium such as air or water.
