Which type of energy is possessed by a body due to its motion?

• A. Potential energy
• B. Kinetic energy
• C. Mechanical energy
• D. Chemical energy

Answer: (B)

Kinetic energy is the type of energy that a body possesses due to its motion. This energy is directly related to the speed and mass of the object. The formula for kinetic energy is given by \( KE = \frac{1}{2} mv^2 \), where \( m \) is the mass of the object and \( v \) is its velocity. This means that as an object moves faster or becomes more massive, its kinetic energy increases accordingly. Potential energy, on the other hand, is related to the position of an object within a gravitational field or any other system where it has the capability to do work as a result of its position. Mechanical energy refers to the sum of kinetic and potential energy in a system, thus it encompasses both types of energy rather than focusing solely on motion. Chemical energy is the energy stored in the chemical bonds of a substance, which is released during a chemical reaction. Thus, kinetic energy specifically describes the energy linked to the motion of a body, making it the correct answer in this context.

The formula for kinetic energy is given by ( KE = \frac{1}{2} mv^2 ), where ( m ) is the mass of the object and ( v ) is its velocity. This means that as an object moves faster or becomes more massive, its kinetic energy increases accordingly.
