Question

Kinesiology studies how the body initiates and controls movement, beginning with the brain

and using interactions of different body systems. The body moves when internal and external
forces act on it. Internal forces are generated within the body, while external forces are generated outside of the body.
Internally, muscles generate force as they contract and bones generate movement. Which
statement accurately represents how forces affect motion in organisms?
O When a muscle relaxes, it applies a pulling force on a bone, causing it to move.
O When a bone relaxes, it applies a pushing force on a muscle, causing it to move.
O When a muscle contracts, it applies a pulling force on a bone, which causes movement.
O When a bone contracts, it applies a pushing force on a muscle, which causes movement.

Answer 1

Answer: When a muscle contracts, it applies a pulling force on a bone, which causes movement

Step-by-step explanation:

The statement that muscle contract is causing application of a pulling force on a bone and that it is causing movement is representing how forces are affecting motion in organisms od the human body.

The process of muscle contract is called contraction. These muscles are attached to bones that are found in the human body and they are attached to them by strong tendons. When it comes to the contraction process, the muscle is pulling on the bone.
