Biomechanics Review Quiz

What is the interrelationship between biomechanical principles and the body for safe movement?

• They are unrelated

• They enhance movement efficiency

• They decrease movement speed

• They cause injury

Which of the following is NOT a way biomechanical principles are applied to human movement?

• Increasing movement efficiency

• Enhancing safe movements

• Reducing balance and stability

• Applying fluid mechanics and force

What is inertia?

• An object's resistance to a change in its state of motion

• An object's ability to change direction quickly

• An object's speed in a vacuum

• An object's mass

What must a sprinter do to overcome inertia?

• Stand still

• Exert force against the ground

• Reduce their speed

• Increase their weight

What is linear motion?

• Motion in a circular path.

• Motion from one position to another in a straight line.

• Motion that is random and unpredictable.

• Motion that involves spinning.

What is the formula for calculating speed?

• s = d/t

• s = t/d

• s = d * t

• s = t * d

What is the formula for calculating acceleration?

• a = (v2 - v1) / time

• a = (v1 - v2) / time

• a = v2 * v1 / time

• a = time / (v2 - v1)

What is the significance of speed in sports like swimming and athletics?

• Time taken is more important than distance

• Distance is more important than time

• Both time and distance are equally important

• Neither time nor distance is important

What is the effect of having a lower center of gravity?

• It makes balance more difficult.

• It makes balance easier.

• It has no effect on balance.

• It increases height.

What does a narrow base of support allow in terms of the centre of gravity?

• The centre of gravity to be stable

• The centre of gravity to fall close to the edge

• The centre of gravity to be in the middle

• The centre of gravity to be high
