At the beginning of its fall, the total energy of the object is equal to its potential energy, which is mgh.

The kinetic energy is zero initially because the object’s velocity is zero at the start of its fall.

It provides a fundamental principle in physics, ensuring that energy is conserved and allowing for predictions and analysis of various physical processes, from simple mechanical systems to complex chemical reactions and nuclear processes.

The gravitational potential energy (PE) of an object at a height (h) above the ground is calculated using the formula: PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h ...

Yes, gravitational potential energy can be negative if the reference point is chosen such that the object’s current height is below it. In this case, the object has less potential energy compared to the reference point.
