Biomechanics Quiz

What happens when the Center of Gravity (COG) is lowered?

• Stability increases

• Stability decreases

• Balance is lost

• Base of Support (BOS) narrows

Which factor does NOT directly influence the trajectory of a projectile?

• Height of Release

• Base of Support (BOS)

• Angle of Release

• Speed of Release

According to Newton's Second Law, what happens when a greater force is applied to an object?

• The object remains at rest

• The object decelerates

• The object accelerates more

• The object changes direction

What is the effect of widening the Base of Support (BOS)?

• Decreases stability

• Increases stability

• Increases speed

• Decreases balance

Which of the following is NOT a principle of Force Summation?

• Lowering the Center of Gravity increases force

• Correct Order of Body Parts optimizes force transfer

What is the effect of increasing the mass of an object on its acceleration, assuming the force applied remains constant?

• Acceleration increases

• Acceleration decreases

• Acceleration remains the same

• Acceleration becomes zero

Which of the following factors does NOT affect the stability of an object?
