Determine which of the following represent potential energy and which represent kinetic energy.

(a) thermal energy

(b) gravitational energy

(c) chemical energy

(d) electrostatic energy

(a)

Interpretation Introduction

Interpretation:

Thermal energy whether represents kinetic energy or potential energy has to be determined.

Concept introduction:

Energy:

Energy is the capacity to do work, and can neither be created nor destroyed.  Generally, chemical reaction almost always either release or absorb energy.

Types of energy:

Kinetic energy is the energy associated with motion.  Thermal energy, mechanical energy, electrical energy, and acoustic energy are categorized in kinetic energy.

Potential energy is the energy results from an object’s position or state.  Gravitational energy, chemical energy, and electrostatic energy are categorized in potential energy.

Explanation of Solution

Thermal energy: The motion of ions, molecules or atoms at microscopic level generates the heat energy...

(b)

Interpretation Introduction

Interpretation:

Gravitational energy whether represents kinetic energy or potential energy has to be determined.

Concept introduction:

Refer to (a).

(c)

Interpretation Introduction

Interpretation:

Chemical energy whether represents kinetic energy or potential energy has to be determined.

Concept introduction:

Refer to (a).

(d)

Interpretation Introduction

Interpretation:

Electrostatic energy whether represents kinetic energy or potential energy has to be determined.

Concept introduction:

Refer to (a).
