As the video states, a person weighs less on the moon than on
the earth. discuss why gravity is a benefit. what would it be like
if the force of gravity were stronger? what if it were equal to
that of the moon? why are gravity and weight related?

True or false a high force means an object is moving fast100 points!

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

Does heating a metal wire increase or decrease its electrical resistance? why?
