What should be done to avoid slipping while walking on ice ?
Since ice is slippery, you cannot exert a large horizontal force on an ice surface without slipping. That makes it easier to fall down. If you were on ice and starting to fall forward, you would instinctively try to push backward on the ice. If you do not slip, by Newton’s Third Law (action = -reaction), the ice will push forward on your feet, helping you to regain your balance. If your feet slip, you could lose your balance and fall forward. If you are stationary, you can stay upright as long as your center of gravity is directly above the area on the ice defined by your feet and the space between them. By pressing on your toes or heels and/or your left or right foot, you can keep yourself balanced. If you take small steps, it is easier to keep this balance and the corrective forces will be smaller, making it less likely that you will slip.
