Question

decreasing the angle of a joint from 90° to 45° would be an example of which of the following? deceleration extension momentum flexion

Explanation:

Flexion is the movement that decreases the angle between two bones at a joint. Here, the joint - angle is decreasing from 90° to 45°, which is an example of flexion. Deceleration is related to a decrease in speed, extension increases the joint - angle, and momentum is a property of moving objects related to mass and velocity.

Answer:

flexion
