Define kinetic energy
Answers
Answer:
energy which a body possesses by virtue of being in motion.
energy which a body possesses by virtue of being in motion."energy above that needed to ionize the molecule is carried away as kinetic energy of the electron ejected"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
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. ... Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive.
