What is biomechanics?

• the study of biological organisms
• numeric calculations and conversions
• forces acting on the human body
• engines and how they run

What are the TWO MAIN benefits that biomechanics has on an athlete?

• Increased performance

• Breaking world records

• Getting new equipment

• Reduced risk of injury

Newton's first law of motion states that 'an object will remain at rest or in it's current state of motion unless ...' what?

• Acted upon by an unbalanced force.

• It's mass is too great.

• It is pushed, kicked or hit.

• There is no gravity present.

Newton's second law of motion states that 'force equals ...' what?

• Mass / Speed

• Mass x Acceleration

• Inertia x Mass

• Mass / Gravity

Newton's third law states that any action will have a(n) _______ and ______ reaction

• Equal and similar
• Equal and opposite
• Equal and different
• Greater and opposite

What information does a velocity give that a speed does not give?

• rate of change of distance

• direction

• units of measurement such as km/h or mi/h

• how fast something travels

What is speed?

• The rate at which an object changes position

• The direction an object is moving

• moving fast

• change in speed or direction
