The gravitational potential energy of a body on the surface of earth is -6.5×10^6 J.what does it statement mean?

This statement means that the body has a gravitational potential energy of -6.5×10^6 Joules when it is on the surface of the Earth. The negative sign indicates that the potential energy is in a downward direction, meaning that the body is in a lower energy state compared to a reference point. This could be due to the body being at a lower height or having a lower mass compared to the reference point.

The gravitational potential energy of a body on the surface of the earth is -6.5×10^6 J means that the body has stored energy due to its position relative to the gravitational field of the earth. The negative sign indicates that the body has the potential to fall and gain kinetic energy, converting its potential energy into motion.

The magnitude of the gravitational potential energy is proportional to the mass of the body and inversely proportional to its height above the ground. The 6.5×10^6 J value indicates that the body has a significant amount of potential energy and could do significant work if allowed to drop or move freely in the gravitational field.
