Why don’t rockets tip over when taking off?
A rocket has two different rotational centers. The center of mass is the point where the rocket balances. The is the point it would rotate around if it were in a vacuum, and as the fuel burns from the back of a solid fuel motor it moves the center of gravity slightly forward.
The Short Answer
A rocket has two different rotational centers. The center of mass is the point where the rocket balances. The is the point it would rotate around if it were in a vacuum, and as the fuel burns from the back of a solid fuel motor it moves the center of gravity slightly forward. The center of pressure, on the other hand, is the point where air forces on the rocket are equal. Adding even a tiny fin moves the center of pressure backwards. Think of it like that gaudy rooster wind vane on a rural farmhouse. Air presses on all of the structure if the structure when it isn't pointed into the wind. The center of pressure only depends on the shape, so it doesn't change as the fuel is burned. Small fins are put on the bottom of a rocket so the center of pressure is behind the center of mass. This means that the force of air on the whole of the rocket's shape turns the rocket if it is disturbed to return it to going in the direction it was launched. Solid fuel rockets become more stable as they fly faster.
