Gravitational potential is always negative due to gravity acting in the opposite direction of where we want to bring that mass. We also use infinity as a zero point. Instead work is done by gravity to bring it from infinity to that point therefore it is negative ]]> 2021-05-11 07:26:52 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512400513 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512401662 Gravitational potential is the amount of energy to move a test mass from a infinite distance to a point within a distance of a larger mass

Gravitational potential is always negative as its value at an infinite distance from a large mass is 0]]> 2021-05-11 07:27:26 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512401662 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402158 Gravitational potential is the work done per unit mass and it is always negative because it takes work to take a mass to infinity hence the opposite is true for a point that is not at infinity ]]> 2021-05-11 07:27:42 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402158 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402929 Gravitational potential is the work done to move a point mass from infinity to that point in a gravitational field ]]> 2021-05-11 07:28:05 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402929 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402969 Gravitation potential is the energy per unit mass required to take a mass from infinity to that point in the field. It is negative because work is already done by the g field to put it there. At infinity it is zero.]]> 2021-05-11 07:28:06 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512402969 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512404325 a) The work required to move a point test mass from infinity to that point.
b) It is defined as the work required from infinity and is 0 at infinity. This means that when a gravitational field provides a force on the object, it gains work, therefore reducing the work required to move the mass below 0.]]> 2021-05-11 07:28:47 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512404325 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512404398 a) gravitational potential is the gravitational constant multiplied by the mass of the planet and then divided by the radius therefore giving us the gravitational potential

b) it's always negative because you need to move a an object from infinity to that point . At infinity the gravitational potential is always zero so to get to the point it will be negative.]]> 2021-05-11 07:28:49 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512404398 https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512406440 Gravitational potential is always negative as work is being done on the point mass to move it from infinity]]> 2021-05-11 07:29:52 UTC https://padlet.com/joesandell/gcnvxxjjip2g4s1j/wish/1512406440
