Which of the following scenarios best exemplifies kinetic energy being converted to thermal energy?
- Rubbing your hands together to create warmth. (correct)
- A magnet attracting a nail.
- Sunlight warming a metal surface.
- A battery powering a flashlight.
Magnetic energy is a form of potential energy due to its capacity to cause movement, such as repelling ferrous metals.
Magnetic energy is a form of potential energy due to its capacity to cause movement, such as repelling ferrous metals.
False (B)
Describe how electrical energy is a form of kinetic energy at a particle level.
Describe how electrical energy is a form of kinetic energy at a particle level.
Electrical energy involves the movement of charged particles, such as electrons, along a conductor like a wire. This movement of particles defines its kinetic nature.
________ energy, such as that from the sun, travels in the form of electromagnetic waves, including UV radiation.
