Verified step by step guidance1
Understand the concept of kinetic energy: Kinetic energy is the energy that an object possesses due to its motion. It is given by the formula: , where is the mass and is the velocity of the object.
Identify the types of energy listed: Thermal energy, Nuclear energy, Potential energy, and Chemical energy.
Relate each type of energy to motion: Thermal energy is related to the motion of particles within a substance. As the particles move faster, the thermal energy increases, which is a form of kinetic energy.
Consider the other options: Nuclear energy is stored in the nucleus of atoms, potential energy is stored energy due to position, and chemical energy is stored in chemical bonds. These are not forms of kinetic energy.
Conclude that thermal energy is the correct answer as it involves the motion of particles, which aligns with the definition of kinetic energy.
