Question

3
when a ball is thonon vertically
upwords, the gravitational potential energy
of the ball​

Answer 1

INCREASES

Gravitational potential erg

$since\bold{U= - \frac{GM}{r}}$

hence if distance increases Potential erg is less negative than before hence it will Increase then before

Hope it helps

Answer 2

Answer:

if an object is thrown upwards, it gains height and loses speed, thus increasing its gravitational potential energy and decreasing its kinetic energy. In this case it is the kinetic energy which is being transformed into gravitational potential energy.
