Question 1

Peak Height Velocity

Answer 1

• This is a stage of rapid height growth, often during adolescence.
• It usually happens during puberty.
• It shows progress in physical maturation.

Question 2

Critical Periods

Answer 2

• Critical periods are key stages when the body or brain is very sensitive to certain stimuli.
• These times are crucial for proper development.
• Example: Learning motor skills and language is easiest during these periods.

Question 3

Motor skills

Answer 3

the ability to use the body’s muscles to perform tasks, such as walking, running, or writing

Question 4

Ideal performance state and provide examples of how athletes describe this state.

Answer 4

• The Ideal Performance State (IPS) is when an athlete performs at their best. It happens when their skills match the challenge, and they are fully focused and in control.

“I was completely in the zone.”
“Everything just clicked and felt easy.”
“I was calm and focused, no matter what was happening.”

Question 5

Statistics

Answer 5

the branch of mechanics that studies objects or bodies in a state of constant, unchanging motion

Question 6

Dynamics

Answer 6

the branch of mechanics that studies changes in the motion of objects or bodies as a result of the actions of forces.

Question 7

Stability

Answer 7

The quality , state, or degree of being stable and capable of resisting in a change of motion

Question 8

Balance

Answer 8

An even distribution of mass enabling someone or something to stay steady

Question 9

Mass

Answer 9

Quantity of matter contained within an object or body

Question 10

Centre of mass

Answer 10

The imaginary middle point around which the mass of an object or person is balanced

Question 11

Base of support

Answer 11

The supporting area beneath an object or body; it’s limits are defined by the points of contact with the supporting surface

Question 12

Momentum

Answer 12

The quantity of motion contained within an object or body; equal to the product of the object’s mass of velocity

Question 13

Velocity

Answer 13

The speed and direction of an object’s movement, calculated by how much its position changes over time.

Question 14

Impulse

Answer 14

The application of a force over a period of time; impulse equals force multiplied by time

Question 15

Torque

Answer 15

The turing effect made when a force is applied to a body at some distance from an axis of rotation

Question 16

Angular momentum

Answer 16

Angular momentum is the amount of rotational motion an object has. It is found by multiplying the object’s angular velocity (how fast it spins) by its moment of inertia (how its mass is distributed).

Question 17

Angular velocity

Answer 17

Angular velocity is how fast something is spinning, measured as the amount of rotation it completes in a certain amount of time.

Question 18

Moment of inertia

Answer 18

is an object’s resistance to changes in how fast it spins. The farther the object’s mass is from its axis of rotation, the larger its moment of inertia.
