Kinetic Energy
What is kinetic energy?
The energy of an object due to its motion.
What is potential energy?
Stored energy ready to be used.
What is an energy transformation?
The process of energy changing from one form to another.
Name the two main types of energy.
Kinetic energy and potential energy.
What is temperature?
A measure of the average kinetic energy of particles in an object.
Give an example of kinetic energy.
A rolling basketball or a running student.
Name one type of potential energy.
Gravitational, elastic, or chemical potential energy.
Describe the energy transformation of a roller coaster.
At the top, it has potential energy; as it goes down, it transforms to kinetic energy.
What is sound energy?
Energy that travels in waves through matter created by vibrations.
How is temperature measured?
In degrees Fahrenheit (°F), Celsius (°C), or Kelvin (K).
How does mass affect kinetic energy?
When mass increases, kinetic energy increases.
What is gravitational potential energy?
The potential energy stored in an object held up high.
How does a pendulum demonstrate energy transformation?
It swings back and forth, changing between potential and kinetic energy.
How does electrical energy work?
It results from moving electrons creating an electric current.
What is thermal energy?
The total kinetic energy present in an object.
What happens to kinetic energy when speed increases?
The faster something moves, the more kinetic energy it has.
Explain elastic potential energy with an example.
Energy stored in a stretched rubber band.
Give an example of energy changing from potential to kinetic.
Jumping up from a crouched position.
What is thermal energy?
The movement of particles in matter.
Explain the difference between temperature and thermal energy.
Temperature measures average kinetic energy; thermal energy measures total kinetic energy.
Describe a real-world scenario that involves kinetic energy.
A flying bird or a car driving down the street.
How is chemical energy stored?
In the bonds between atoms.
Explain energy conservation in a closed system.
Energy is transferred between objects without being created or destroyed.
Describe nuclear energy and give an example.
Energy from changes in an atom's nucleus; example: nuclear power plants.
How does motion relate to kinetic energy?
Motion is necessary for an object to have kinetic energy.
