Because you don't have suction cups on your feet. Actually, even if you did, it's doubtful that your muscles would be strong enough. To stand up without leaning forward, your center of gravity is well back from your feet. So if you tried it you'd tip over backward. If your feet were stuck to the floor you wouldn't tip over, but the way your muscles are attached probably wouldn't give you enough leverage to actually stand up.

Why is it not possible to sit upright in a chair rise to one's feet without first leaning forward?

Your center of gravity is too far to the rear. Leaning forward transfers the weight to the front where your legs can lift you up to stand.


Is it possible for us to get up from a chair without bending forward?

Standing requires your feet to be under the center of balance. Otherwise you will fall over.When you stand up from a chair, your feet are normally somewhat in front of you. You compensate by leaning forward to move your center of balance forward.So... standing up from a chair without leaning forward might be achieved by one (or a combination) of the following:With a chair that has open legs, put your feet as far back as possible, perhaps balancing on your toes and stand straight up.Scoot forward in the chair to effectively move your center of balance forward to the point where you can stand up.Support yourself with your arms or some device until you can move forward enough to get your center of balance under yourself.

What is the center of gravity chair test?

It is a fun little test that demonstrates the differing centers of gravity between a male and a female.Place a chair against the wall and you stand in front of it with your feet shoulder length apart and firmly planted on the ground. You bend over - keeping your back as straight as possible - and put your head against the wall. Stand up while lifting the chair to your chest.A male's center of gravity is around his waist area, thus lifting the chair in such a position will more than likely be difficult (Sort of like a top heavy thing...Ha). There are very few males who can do this successfully.A female's center of gravity is around her hip area, causing her to be "anchored" down in a sense. Even so, there are a few girls who find this difficult. From what I have seen, it seems girls who are shorter tend have some difficulty.

How do you do an elevator on the Call of Duty Modern Warfare 2?

sorry you cant as its been patched. but basically you have to find the glitch under the very edge of a ledge. simply walk straight up to a ledge where you can crouch under but cant stand up under. so walk up to a ledge. change stick layout to legacy southpaw rotate your player slightly clockwise or anti clock. if you move clockwise you have to move to the left to where you cant stand under the ledge. and vice versa if anti clock if you moved to the part where you cant stand, you have to now find the part in-between the ending of the ledge, where you can stand and cant stand. its hard to explain but there are great tutorials on you tube. :^)
