Question

The total energy possessed by an object located near the earth surface is equal to the
1. Sum of the potential energy and the mechanical energy
2. Infinity
3. Zero
4. Sum of the potential energy and the kinetic energy

Answer 1

Correct Answer - Option 4 : Sum of the potential energy and the kinetic energy

The correct answer is Sum of the potential energy and the kinetic energy.

• An object's total mechanical energy is the sum of its kinetic energy and potential energy. Mechanical energy exists in two forms: kinetic and potential.
• The sum of these two values is the total quantity of mechanical energy.
• The kinetic energy of an object is the energy that it possesses due to its motion. The S.I unit of kinetic energy is Joules.
• Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. 
• The S.I unit of potential energy is Joules.
