Definition of Kinetic Energy:
- Kinetic energy is the energy possessed by a body on account of its motion.
- It is a form of energy that an object possesses due to its motion.
Explanation of the Options:
A. Mechanical Energy:
- Mechanical energy is the sum of potential energy and kinetic energy.
- It includes both the energy of motion (kinetic energy) and the energy stored in an object's position (potential energy).
- While kinetic energy is a component of mechanical energy, it is not the only form of mechanical energy.
B. Potential Energy:
- Potential energy is the energy that an object possesses due to its position or state.
- It is stored energy that can be converted into other forms of energy, such as kinetic energy.
- While potential energy can be converted into kinetic energy, it is not specifically related to the energy possessed by a body in motion.
C. Kinetic Energy:
- Kinetic energy is the energy possessed by a body on account of its motion.
- It is directly related to the mass and velocity of an object.
- The formula for calculating kinetic energy is KE = 1/2 mv^2, where KE represents kinetic energy, m represents mass, and v represents velocity.
D. Magnetic Energy:
- Magnetic energy refers to the potential energy stored in a magnetic field.
- It is related to the ability of a magnetic field to do work or exert a force on other magnetic objects.
- Magnetic energy is not directly related to the motion of a body and is not the correct answer in this case.
Conclusion:
Based on the given options and the definition of kinetic energy, the correct answer is C: Kinetic energy. Kinetic energy is the energy possessed by a body on account of its motion, while the other options are either different forms of energy or not directly related to the motion of a body.
