Question

Sit down on a chair with both feet flat on

the floor. Now kick your right leg forward so that it is straight out in front of you,
What movement occurred at the knee?

Answer 1

When you kick your leg in front of you by using your knee and not the hip that movement is called extension. Every movement that makes a joint move in such a way that the body part moves away from your center is called extension. When we extend the knee joint our quadriceps muscle contract and pulls the shin upwards.
