Velocity is calculated by

distance divided by time

Acceleration is calculated by

Velocity divided by time

How do we calculate the total force of resistance at a given time point?

Instant acceleration plus gravity acceleration times mass = total force
Pg 79

How do we calculate torque

torque is equal to force times distance

how do we calculate momentum

velocity times mass

how do we calculate work

Force applied times distance moved

define power

the rate of work

how do we calculate power

force applied times velocity
or
work divided by time

Positive power can be produced only by ______.

concentric contractions.

Length tension effect plus muscle angle of pule = __________.

strength curve

Describe the length tension effect

Muscle produces the greatest tension at near resting length.

Less tension in the muscle is produced above or below resting length
Pg 83

The most efficient muscle function of torque is at _______%

90%

If not all the muscle force applied goes into producing the total ROM the remainder force is a applied at __________ or ________.

Dislocating force
stabilizing force

explain the strength curve.

pg 84

when velocity is constant resulting in zero acceleration resistance is completely in the _________

Weight lifted

The point at which muscle contraction is likely to fail during lifting a weight is termed_________.

Sticking region

define torque

the tendency of a force to rotate an object about an axis, fulcrum, or pivot

describe the stretch shortening cycle

eccentric contraction the potentiates concentric contraction.

"a wind up action in the opposite movement followed by the intended movement"
