Potential v. Kinetic Energy
What is the difference between kinetic and potential energy?
Kinetic = energy of motion
Potential = associated with relative position of something
Why do hot objects have high temperatures?
As thermal energy is added to an object, the object's molecules move faster. When the molecules move faster, they have more kinetic energy and the temperature increases.
A group of lawmakers who govern a city or town.
What is a city council?
Give two examples from everyday life where potential and kinetic energy is used.
Acceptable answers: a rock sitting on a cliff edge, a stretched rubber band, movement of planets, etc.
What is mass and speed?
The motion of atoms or molecules within a substance.
What is thermal energy?
A city or town government made up of a city council and a mayor.
What is a municipal government?
What are two ways you can reduce the transfer of thermal energy in everyday life?
Acceptable answers: wearing multiple layers of clothing, adding insulation to walls, roofs, etc.
These variables determine the amount of potential energy an object has.
The object's position and its mass.
Matter in which atoms are closely spaced and vibrate in a fixed position.
What is a solid?
What is a mayor’s role as the chief executive in a municipal government?
Overseeing the day-to-day operations of the city, including managing various departments like police, fire, public works, and enforcing local laws, often by appointing department heads and presenting a budget to the city council for approval; essentially acting as the leader of the city's executive branch, setting policy direction and ensuring its implementation
If you touch a block of ice it feels cold, which way is the thermal energy transferred?
From your hand to the ice
This makes stuff happen.
What is energy?
Matter in which atoms vibrate so much that they are far apart.
What is gas?
What are a mayor’s job responsibilities?
Serving as the chief executive officer of a city, overseeing city services, managing the city budget, representing the city at official events, leading the city council, addressing citizen concerns, and responding to emergencies, essentially acting as the public face of the municipality and advocating for its needs to other government entities

What is gravity?
The transfer of thermal energy from a hotter area to a colder area.
What is heat?
