Question

potential energy and kinetic energy​

Answer 1

Explanation:

Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2. As the fall of the object continues, the potential energy would decrease while the kinetic energy would increase.

A hammer: when raised up has potential energy (the energy of position or state) when falling down has kinetic energy (the energy of motion)

Answer 2

Potential Energy - the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

Kinetic Energy - In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
