[Grade 12 Physics] Gravitational/circular motion #2

[QUOTE="kuruman, post: 6333289, member: 192687"] Weight is the force with the which the Earth, or the asteroid in this case, attracts the object. Apparent weight is the force that a bathroom scale would measure. Contrary to popular belief, a bathroom scale measures the normal force exerted on its surface, not the weight of an object placed on it. When you push on a bathroom scale with your hand, it does not display your weight, does it? Thus, if you stand on a bathroom scale in a moving elevator, it will display more than your weight if the elevator is accelerating up, less than your weight if accelerating down and your weight if moving at constant speed up or down or is at rest. The same situation applies here except that the normal force is different from the weight not because the mass is accelerating in a straight line but because it is going around in a circular path while maintaining contact with the surface.
