Frequently Asked Questions
What is kinetic energy?
Kinetic energy is the energy of motion. Any moving object has kinetic energy proportional to its mass and velocity squared.
What is potential energy?
Potential energy is stored energy due to position. Gravitational potential energy depends on mass, height, and gravity.
Why is velocity squared in kinetic energy?
This comes from the work-energy theorem. Doubling velocity quadruples kinetic energy because work = force × distance.
What is energy conservation?
Energy cannot be created or destroyed, only converted. Kinetic and potential energy can transform into each other.
What units are used for energy?
The SI unit for energy is the Joule (J). Other units include calories, BTU, and kilowatt-hours.
