16
Q

force

A
  • a push or pull that produces, arrests, or modifies a motion.
17
Q

torque

A

the rotary equivalent to force defined by the product of a force times its moment arm.

18
Q

Identify and describe the two characteristics that determine the amount of torque occurring at a joint

A
  • distance between the force and the axis of rotation.
19
Q

1st lever

A

similar to a see-saw with its axis of rotation located between the internal and external force. EX. the head and neck.

20
Q

2nd lever

A

IMA is longer than the EMA. EX. plantarflex

21
Q

3rd lever

A

: IMA that is smaller than EMA. EX. bicep curl.

22
