Types of Energy
The energy that flows through copper wires when plugged into the wall.

This law states: "Energy cannot be created or destroyed only transferred or transformed."
What is the law of conservation of energy?
When energy moves to a new object and stays the same type.
What is energy transfer?
The stored energy an object has due to its position.
The force that transforms mechanical energy into thermal energy.
What is friction?
The energy that is stored in the bonds of atoms and molecules.
What is chemical energy?
Motion that is never ending or changing.
What is perpetual motion?
When energy moves to a new object and changes type.
What is energy transformation?
The active/working energy an object has due to its movement.
What is kinetic energy?
FREE FOR ALL
Heat transfer that occurs through direct contact.
What is conduction?
The type of energy that eyes can detect.
What is light energy?
In this type of system ALL the stored potential energy will become kinetic energy (hint: this does not exist).
What is a perfect system?
FREE FOR ALL
Identify the MAIN energy transfer or transformation: A bat hits a baseball.
What is the transfer of mechanical energy (bat to ball)?
All of the mechanical energy at the highest point of the swing of a pendulum when it is about to turn around.
What is potential energy?
Heat transfer that occurs in currents of liquids and gasses.
What is convection?
FREE FOR ALL
The energy an object has based on movement or position.
What is mechanical energy?
These are types of energy that mechanical energy transforms into as a mechanical system's motion stops.
What are heat (thermal), light, and sound (mechanical)?
Identify the MAIN energy transfer or transformation: When a generator creates electricity.
What is the transformation of mechanical energy to electrical energy?
The variable that affects an objects potential AND kinetic energy.
What is mass?
Heat transfer that does not require matter. This thermal energy can travel through a vacuum.
What is radiation?
The energy an object has because of the movement/vibration of molecules.
What is thermal energy?
The reason loud engines are less efficient.
What is the transfer of mechanical energy/transformation of mechanical energy to sound/thermal energy
Identify MAIN energy transfer or transformation: When a person kicks a kickball and a THUNK sound is made.
What is the transfer of mechanical energy (foot to kickball)?
FREE FOR ALL
The variable that affects kinetic energy exponentially.
What is velocity?
The units for measuring thermal energy.
What are Calories or Joules?
