Question

electric energy
text about electric energy, electrons, electric current, simple circuit
explain why is electric energy a type of kinetic energy?
image of a hockey player with a puck, and two text boxes:
\the mechanical energy of the hockey puck is the sum of the puck’s kinetic energy (due to its mass and speed) and gravitational potential energy (due to its mass and height above the ground).\
\thermal energy is the sum of the kinetic energy and potential energy of the particles that make up the puck.\

analyze what types of energy are included in the hockey system?

Explanation:

To determine the energy types in the hockey system, we analyze the provided information:

1. Mechanical Energy (Kinetic + Gravitational Potential): The text states the hockey puck’s mechanical energy is the sum of its kinetic energy (from mass and speed) and gravitational potential energy (from mass and height above the ground).
2. Thermal Energy: The text defines thermal energy as the sum of the kinetic and potential energy of the particles making up the puck.
3. Potential Energy (from particle interactions): Implied in thermal energy (potential energy of particles) and gravitational potential energy (of the puck).
4. Kinetic Energy (of the puck and its particles): The puck’s motion gives it kinetic energy, and the particles in the puck have kinetic energy (part of thermal energy).

Answer:

The hockey system includes:

• Mechanical Energy (sum of the puck’s kinetic energy and gravitational potential energy).
• Thermal Energy (sum of the kinetic and potential energy of the particles in the puck).
• Kinetic Energy (of the moving puck and its internal particles).
• Potential Energy (gravitational potential energy of the puck and potential energy of the particles in the puck).
