The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes

What determines the amount of inertia an object has

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
