Detailed explanation-1: -A moving car possesses mechanical energy due to its motion (kinetic energy).

Detailed explanation-2: -Kinetic energy is the energy a person or an object has due to its motion-in this example, the falling apple. A parked bike on top of a hill has potential energy, which becomes kinetic energy once you start riding it downhill.

Detailed explanation-3: -Let’s use another example: Imagine there is a book on a table. When the book is at rest, it has potential energy. But when you accidentally knock it off the table, this potential energy will turn into kinetic energy while the book falls since it’s in motion.

Detailed explanation-4: -A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work. An object that is not moving has zero kinetic energy.
