Question

Why you cannot get up from chair without bending body and legs

Answer 1

Since people have a mass core like all masses, and when a person sits in a chair, the center of his mass is around the center of the legs of the chair. But he / she must move his or her center of mass to his or her feet if he or she tries to stand up. So people lean forward to maintain balance when standing on the right chair.

EXPLANATION:

• The centre of mass is responsible for this. When an individual sits on a chair, his mass-center is in the centre of the legs of the chair.
• But he must switch the center of his mass to his feet as he tries to stand up. So while standing up from the right chair, we bend little forward to maintain balance.
