6. The image to the right shows a moment of inertia demonstrator device. This device can spin its four arms
around its center. On each arm is a weight that can be
adjusted closer or farther from the center of rotation.
A student says, “Moving the weights away from the center
of mass does not change the moment of inertia, since the
total diameter of the device does not change." Do you
agree with this statement? Explain.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
