The kinetic energy (KE) of the object at a given instant when its velocity is v is given by 1/2mv². This represents the energy due to the object’s motion.

The total energy of the object at the height h is its potential energy, which is mgh. At this point, the kinetic energy is zero, so the total energy is entirely due to its potential energy.
The kinetic energy is zero at the start because the object is initially at rest. Since kinetic energy is given by 1/2 mv², and the initial velocity (v) is zero, the kinetic energy is also zero.
In both the zigzag path and the straight vertical path, the work done by gravity is the same. Even though the zigzag path is longer, the vertical height difference h between positions A and B remains constant. Therefore, the work ...
The work done by gravity is the same for both paths. It is given by mgh, where m is the mass of the block, g is the acceleration due to gravity, and h is the vertical height difference between positions ...
Energy is transferred to the rubber band when it is stretched, becoming its potential energy.
Transferred energy becomes potential energy if it doesn’t alter an object’s velocity.
Energy gets stored when work is done on an object, transferring energy to it.
The work done by gravity depends on the difference in vertical heights between the initial and final positions of the object. It is independent of the path taken to move the object between these two points.
Potential energy signifies the stored energy in objects, whether it’s a wound-up spring or a stretched rubber band, resulting from their position or configuration.
