Final answer:
Atomic energy is produced through nuclear reactions such as fusion and fission, where a small amount of mass is converted into energy. The kinetic energy of a body depends on its mass and velocity.
Step-by-step explanation:
Atomic energy, also known as nuclear energy, is produced through nuclear reactions. The two main types of nuclear reactions are nuclear fusion and nuclear fission. In nuclear fusion, atomic nuclei are combined to form a heavier nucleus, while in nuclear fission, a nucleus is split into smaller nuclei. The energy produced in these reactions is the result of the conversion of a small amount of mass into energy, as described by Einstein's famous equation E=mc².
The kinetic energy of a body depends on two factors: its mass and its velocity. The kinetic energy of an object can be calculated using the equation KE = 1/2 mv², where KE represents kinetic energy, m represents mass, and v represents velocity. For example, if a car is traveling at a higher velocity or has a greater mass, it will have a higher kinetic energy.
