Biomechanics

What is Biomechanics?

• Study of biological mechanics

• Study of motion & the effects of forces relative to the body

• Study of sports

• Some thing you do in PE Studies

Angular motion occurs when...

• rotate in a linear motion

• all body parts move in the same direction at the same speed

• turn about an axis of rotation

• form an angle

What is Displacement?

• The distance travelled from start to finish

• The distance from start to finish

• The furthest point from the start

• The closes point from the start

What is the formula for speed?

• distance/time

• velocity/time

• displacement/time

• mass x acceleration

What is the formula for acceleration?

• velocity/time

• change in velocity/time

• speed/time

• change in speed/time

What is zero acceleration?

• velocity is increasing

• velocity is decreasing

• velocity has no change

• velocity increases, has no change, then decreases

In relation to Summation of Forces, what is power vs accuracy? Pick 2 answers

• power- more segments used. Usually sequential

• power- less segments needed. Usually simultaneous

• accuracy- more segments used. Usually sequential

• accuracy- less segments needed. Usually simultaneous

What is Simultaneous Summation of Forces?

• Where body parts are moved in sequence to produce a force

• Where body parts move at the same time to produce a force

What is sequential movement (summation of forces)?

• Where body parts are move together to produce a force

• Where body parts are moved in sequence to produce a force

In relation to Sequential Movement, what body parts or muscle groups move first?

• Smallest

• Largest

• All together

• Depends on the sport/action
