What is energy?
The ability to do work or cause change.
What are the two main types of energy?
Kinetic (moving) and Potential (stored).
What is kinetic energy?
Energy of motion (e.g. a rolling ball).
What is potential energy?
Stored energy due to position (e.g. a rock at the top of a hill).
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only changed from one form to another.
What are some forms of energy?
Mechanical, thermal, chemical, electrical, nuclear, light.
What is thermal energy?
The energy of heat or temperature—caused by particle movement.
How does energy transfer?
Through conduction (touch), convection (fluid movement), and radiation (waves).
What is work in scientific terms?
When a force moves an object over a distance (Work = Force × Distance).
