If I sit on a chair with my legs off the ground and I suddenly jerk my body forward, I move the chair forward. Why am I able to do this? Static friction might be a factor but if both the chair and I are one system how did I start moving in the first place? Are there any other factors at play besides static friction? any input is appreciated, thanks.
In: Physics
Sudden movement of your centre of gravity in one direction and then holding the chair overcomes the static friction of the chair on the floor. Slowly moving your weight back keeps within the limit so the chair stays still. Repeat the cycle and you move across the room. It wouldn’t work as well on ice or a chair with castors.
