PQ 12.2 STABILITY (PRINCIPLE 1)

What is the concept related to resistance to rotation?

• Position of the Centre of Mass

• Mass

• Centre of Mass

• Base of Support

Where is the centre of mass located when an individual stands upright?

• At the level of the head

• At the level of the knees

• At the level of the chest

• At the level of the navel

What is the imaginary point around which an individual's mass is concentrated?

• Position of the Centre of Mass

• Mass

• Centre of Mass

• Base of Support

What enhances the stability of football linemen?

• Increasing the mass

• Moving the centre of mass outside the base of support

• Lowering the centre of mass

• Narrowing the base of support

What is the most stable stance for football linemen?

• One hand in contact with the ground

• Both feet in contact with the ground

• No hands or feet in contact with the ground

• Both hands in contact with the ground

What does the line of gravity represent?

• The stability of an individual

• The resistance to rotation

• The base of support

• The position of the centre of mass

What happens when the position of the centre of mass moves outside the base of support?

• The individual becomes lighter

• The individual becomes more stable

• The individual becomes more massive

• The individual becomes less stable

What does the narrow base of support in combination with the high centre of mass indicate?

• Stability

• Increased mass

• Resistance to rotation

• Instability

What is the principle of stability applicable to?

• Only physical activities

• Only work-related tasks

• Every movement, task, or activity

• Only sports

What does the greater mass or weight of an individual result in?

• More resistance to change in linear motion

• No change in resistance to change in linear motion

• Less resistance to change in linear motion

• Increased stability
