What affects the speed of a falling object?

The mass of a falling object will affect the speed at which it falls. Additionally, the shape or geometryof that object will also have an effect. The shape of a falling object will have a dramatic effect on the amount of dragthat the object will experience. Consider that a flat piece of cardboard will fall more slowly than a glass ball of the same mass, and it will be more easy to visualize how drag is a function of shape.

=======================================

Beulah the Buzzer gagged on the first sentence of the response above, and

Signor Galileo rotated 2pi in his crypt.

The mass of a falling object will NOT affect the speed at which it falls.

The remainder of the response above is correct and well stated, provided only

that the objects are falling through air. If not, then neither their shape nor their

geometry affects their rate of fall either.
