Energy Basics
What is Energy of Motion?
Kinetic Energy
Energy changing from one form to another is called this...
Energy transformation
Energy transfer from warmer to cooler objects is called this
Heat
The smallest unit of an element.
Atom
This determines the properties of a substance.
Structure
What is the type of energy stored due to position or condition?
Potential Energy
A lamp converts electrical energy into these two forms
Light energy and thermal energy
Heat transfer through direct contact.
Conduction
Two or more atoms bonded together.
Molecule
Diamond and graphite are both made of this element.
Carbon
What does the Law od Conservation of Energy states?
Energy cannot be created or destroyed
What type of potential energy changes into kinetic energy when a bike is riding downhill?
Gravitational Potential Energy
Heat transfer by movement of fluids (liquids and gases)
Convection
A substance made of two or more different atoms in fixed ratios.
Compound
Same atoms, different arrangements result in this.
Different Properties
What are two factors that affect kinetic energy?
Mass and Speed
In a battery-powered toy, chemical energy turns into what type of kinetic energy?
Electrical Energy
When two objects reach the same temperature, it's called...
Thermal Equilibrium
A repeating pattern of atoms in a solid (like salt or diamond)
Extended Structure
CO2 and CO: which one is dangerous?
CO
A stretch rubber band has this specific type of potential energy.
Elastic Potential Energy
Flashlight (Name the transformation)
Hint:____ energy --->____ energy --->____ energy + ____ energy
chemical → electrical → light + thermal
Difference: temperature measures this, while thermal energy measures this
average energy vs total energy
Why do scientists use models?
to visualize things too small to see
O2 and O3: which one is dangerous?
O3
