Question

What do you mean by kinetic energy?

Answer 1

Answer:

"To accelerate an object we have to apply force. To apply force, we need to do work. When work is done on an object, energy is transferred and the object moves with a new constant speed. The energy that is transferred is known as kinetic energy and it depends on the mass and speed achieved.

The definition of kinetic energy in Physics

“Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.”

Kinetic energy is a scalar quantity. Kinetic energy is completely described by magnitude alone."

Answer 2

Answer:

Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions.
