It is better to have less body parts involved in sequential motion.

True

False

Linear Motion is where

all body parts move in the same direction, same distance, at the same time.

all body parts move around a fixed axis

displacement is divided by time

distance is multiplied by speed and then divided by the velocity of the moving object

An example of Instantaneous speed for a discus throw is ...
(see Coneqt lesson 1 of biomechanics to understand Instantaneous speed)

the amount that it accelerates as it leaves the throwers hand

the speed of the discus while it is in contact with the throwers hand

the speed (km/per) of a discus at the 10 meter mark of it's flight

the average speed of the discus over the enter throw

True

False

True

False

Which one of the following is not a principle of sequential movement to produce maximal force

all body parts must move at the same time to generate maximal velocity

Each body part should be stable so that the next body part accelerates around a stable base to transfer momentum

The stronger and larger muscles of the thighs and trunk are moved first followed by the smaller and faster muscles

Follow through is important to prevent deceleration of last segment and safe dissipation of force
