Feedback and Biomechanics

A baseball pitch is an example of

• simultaneous force summation

• external force production

• sequential force summation

• Impulse

Impulse =

• Mass X acceleration

• time X velocity

• Mass X velocity

• force X time

A track athlete runs 1 and a half laps of a running track. Their displacement is

• 200m

• 600m

• it would require a straight line measurement from start to end position

• 400m

the preferred angle of release when throwing for distance is

• 50 degrees

• 40 degrees

• 35 degress

• 45 degrees

To increase stability, a footballer being tackled would ideally

• raise their COG

• narrow their base of support

• lower their COG

• move their COG outside their base of support

This image represents which class lever?

• 1st class lever

• 2nd class lever

• 3rd class lever

This baseball pitcher is demonstrating which type of lever at the shoulder?

• 1st class
• 2nd class
• 3rd class
• 4th class

What is the base of support?

• The weight of an object on a surface.
• The area beneath an object or person that provides stability.
• The height of an object above the ground.
• The force applied to an object during movement.

How does a wider base of support affect an athletes stability?

• A wider base of support makes an athlete more prone to falling.
• A wider base of support has no effect on stability.
• A wider base of support decreases an athlete's stability.
• A wider base of support enhances an athlete's balance & stability.

What is a force in biomechanics?

• A force in biomechanics is the weight of an object.
• A force in biomechanics is a measurement of speed.
• A force in biomechanics is a type of energy.
• A push or a pull that causes movement or change
