Just before an object reaches the ground, its gravitational potential energy is nearly zero because its height is minimal. Conversely, its kinetic energy is at its maximum due to the object’s maximum velocity. The total mechanical energy, initially all potential energy, has entirely converted into kinetic energy, assuming negligible air resistance.
At the start of its fall, the object's kinetic energy is zero because its initial velocity is zero. All of its mechanical energy is in the form of gravitational potential energy, which then transforms into kinetic energy as it falls.

In both the zigzag and straight vertical paths, the work done by gravity on the block from position A to position B is the same. This is because gravitational work depends only on the vertical displacement between the initial and final positions, not the path taken. Thus, regardless of the path's coRead more
In both the zigzag and straight vertical paths, the work done by gravity on the block from position A to position B is the same. This is because gravitational work depends only on the vertical displacement between the initial and final positions, not the path taken. Thus, regardless of the path’s complexity, the gravitational work remains consistent.
If transferred energy doesn’t change an object's velocity, it can alter other forms of energy, such as increasing potential energy, causing deformation, generating heat, or overcoming friction, depending on the context.

The work done by gravity when an object is moved from one height to another is determined by the vertical displacement and the object's weight. It is calculated as the product of the object's mass, gravitational acceleration, and the change in height (W = mgh).

See lessWhy is the kinetic energy of the object zero at the start of its fall?
At the start of its fall, the object's kinetic energy is zero because its initial velocity is zero. All of its mechanical energy is in the form of gravitational potential energy, which then transforms into kinetic energy as it falls.
