Which of the following statements cannot be supported by Kepler's laws of planetary motion? A planet's distance from the sun will not be the same in six months.

A planet's speed as it moves around the sun will not be the same in six months.

The rotational speed of the four smallest planets can be determined using the rotational speeds of the four largest planets and their orbital periods.

The average distance of Saturn can be calculated using the average distance of Neptune and the orbital period of both planets.

good for her? ? where is the question?

what are the statements? x

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
