<h3>
What is Kinetic energy?</h3>
- Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
- An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
- The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.
