Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). When an object falls, at least part of its potential energy is converted to kinetic energy, the energy due to an object's motion Kinetic energy is the energy of motion of an object or particle, and potential energy is the energy associated with the position of an object or particle.

In physics, kinetic energy is the energy an object has due to its motion
It is defined as the work required to accelerate a body of a given mass from rest to a certain velocity
Once the mass reaches the velocity, its kinetic energy remains unchanged unless its speed changes. Mechanical energy is the sum of kinetic energy, the energy of motion, and potential energy, the energy stored due to an object’s position or structure It’s a key concept in physics, illustrating how energy is conserved and transferred between objects and forms. Ke is the energy of an object or a system’s particles in motion
When you drop the ball, gravity moves it from your hand to the ground That movement is called kinetic energy The ke of an object is relative to other stationary and moving objects present in its immediate environment. Kinetic energy is the energy an object has because of its motion and is also measured in joules (j)
Due to the principle of conservation of energy, energy can change its form (potential, kinetic, heat/thermal, electrical, light, sound, etc.) but it is never created or destroyed.
The sum of this potential energy and kinetic energy is called mechanical energy In other words, it is the energy an object has because of its motion or position or both motion and position. In other words, mechanical energy is the sum of an object’s kinetic and potential energy This means that an object has mechanical energy whether it is moving or staying in position relative to a zero potential energy position.
Kinetic energy is the energy of motion found in moving objects like a car or atoms Potential energy depends on an object's position, like a sled on top of a hill Energy can change forms but is always conserved, like in a swinging pendulum.
