Energy Basics
The ability to do work or cause change.
What is energy?
Energy of motion.
What is kinetic energy?
The total energy of motion and position of an object.
What is mechanical energy?
Energy caused by the movement of charges through a wire.
What is electric energy?
Energy when a swing moves back and forth.
What is kinetic and potential energy?
Energy can cause this to an object (hint: two things).
What is work or change?
Stored energy due to position or condition.
What is potential energy?
This type of energy increases as particle motion increases.
What is thermal energy?
The energy stored in the nucleus of atoms.
What is nuclear energy?
A lit stove burner produces this kind of energy.
What is thermal energy?
This type of energy depends on whether it is stored or in motion.
What is potential or kinetic energy?
A stretched rubber band has this type of potential energy.
What is elastic energy?
When you rub your hands together and they get warm, you are converting this energy into thermal energy.
What is mechanical energy?
Lightning is an example of this type of energy.
What is electric energy?
A roller coaster at the top of a hill has this kind of energy.
What is gravitational potential energy?
Name two broad categories of energy.
What are potential energy and kinetic energy?
A rolling ball has this type of energy.
What is kinetic energy?
The faster the particles move, the __________ the object becomes.
What is hotter?
The sun produces its energy through this process.
What is nuclear fusion?
A stretched bow has this energy, which transfers to kinetic when the arrow is released.
What is elastic potential energy?
Which type of energy increases when an object is raised higher in a gravitational field?
What is gravitational potential energy?
Compare a ball at the top of a hill vs. rolling down. Which type of energy does it have in each situation?
At the top: potential energy. Rolling down: kinetic energy.
A moving car demonstrates this kind of combined energy.
What is mechanical energy (kinetic + potential)?
This type of power plant splits atoms to release energy.
What is a nuclear power plant?
Which two types of energy are most present when turning on a lamp?
What are electric energy and light/thermal energy?
