Mechanical energy of a body includes _______.

Correct option is C

The correct answer is (c) Both potential energy and kinetic energy

Explanation:

• Kinetic energy is just one part of mechanical energy. Mechanical energy is the sum of both kinetic energy and potential energy.
• Heat energy is a form of thermal energy and is not included in the concept of mechanical energy. Mechanical energy involves kinetic and potential energy, not thermal energy.
• Mechanical energy is the sum of kinetic energy (energy of motion) and potential energy (energy of position). It represents the total energy associated with the motion and position of an object.
• While potential energy is an important part of mechanical energy, it does not represent the total mechanical energy, which includes both potential and kinetic energy.

Information Booster:

Mechanical Energy: Mechanical energy is a form of energy that is associated with the motion or position of an object. It can be expressed as:

                               Mechanical Energy=Kinetic Energy + Potential Energy

Kinetic Energy (KE): Energy due to motion, calculated as $$KE = \frac{1}{2} mv^2$$​, where m is the mass and v is the velocity of the object.

Potential Energy (PE): Energy due to position, commonly gravitational potential energy, calculated as $$PE=mgh$$​, where m is the mass, g is the acceleration due to gravity, and h is the height above a reference point.
