|
Energy can be kinetic and move matter.
|
|
|
Chemical energy is potential energy stored in chemical bonds.
|
|
|
Mechanical energy is indirectly involved in moving matter.
|
|
|
Radiant energy directly involves electromagnetic waves.

Detailed explanation-1: -Mechanical energy; Energy directly involved in moving matter. Radiant (electromagnetic) energy; Is energy that travels in waves.
Detailed explanation-2: -There are two types of mechanical energy – motion (kinetic energy) and stored (potential energy).
Detailed explanation-3: -The energy associated with an object’s motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
Detailed explanation-4: -Mechanical energy can take the form of either kinetic energy, which is energy due to an object’s motion, or potential energy, which is stored energy due to an object’s position.
