Identical spheres are dropped from a height of 100 m above the surfaces of both Planet
X and Planet Y. The position of the spheres as a function of time is recorded as the
spheres fall. These data are shown in the graphs above. Which planet exerts a greater
gravitational force on the sphere, and what evidence supports this conclusion?

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

b.transmitters send radio waves, and receivers capture radio waves.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
