Explanation:
tilting it will raise the height of its center of gravity.
KE = 1/2 x 80 x 60^2
KE = 144000
answer:
yes
explanation:
At a separation of the surface of Earth (r=6400km) gravity wants pull the test mass closer and closer. ... So the work done by gravity is NEGATIVE. The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy.
