Q. Which of the following is/are correctly matched?

1. Kinetic energy- motion
2. Potential energy- position
3. Mechanical energy: kinetic energy + heat energy

Select the correct answer from the codes given below:
Answer: Only 1 and 2
Notes: The various forms include mechanical energy (potential energy + kinetic energy), heat energy, chemical energy, electrical energy and light energy. The kinetic energy of a body moving with a certain velocity is equal to the work done on it to make it acquire that velocity. The energy gets stored due to the work done on the object. The energy transferred to an object is stored as potential energy if it is not used to cause a change in the velocity or speed of the object. The potential energy possessed by the object is the energy present in it by virtue of its position or configuration.
