Hi
user
Hello! How can I help you today?
assistant
I'm learning about energy in my science class. What are the main types of energy?
user
There are several main types of energy, including kinetic energy (the energy of motion), potential energy (stored energy), thermal energy (the energy of heat), electrical energy, and chemical energy.
assistant
That's helpful. What's the law of conservation of energy?
user
The law of conservation of energy states that energy can't be created or destroyed, only converted from one type to another. This means that the total energy in a closed system remains constant over time.
assistant
So, when I roll a ball, its potential energy becomes kinetic energy?
user
Exactly. As the ball rolls down a hill, its potential energy (stored energy due to its height) is converted into kinetic energy (the energy of motion).
