This pull towards the center of the earth is the force that keeps our feet on the ground
Gravity
Sitting still is a what kind of energy?
Potential
this type of wave is created by vibrations that our ears detect.
this is the dense central core of an atom that contains both protons and neutrons.
nucleus
This is a temperature at which a liquid turns into a solid like ice
Freezing point
The Force acts in the opposite direction of a moving object, slowing it down when two surfaces rub together,
This type of energy is the energy of motion, which increases an object to move faster.
Kinetic energy
this happens when light bounces off a smooth surface, like a mirror, allowing you to see yourself.
Reflection
negativly charged subatomic particles zip around the outside the nucleus of an atom.
Electron
The process that occurs when a liquid turns into a gas.
Evaporation
this tells you how fast a object is moving.
Speed
Foods and batteries both store energy in a form, which can be released during a reaction.
Chemical energy.
This is the bending of light as it passes from one material to another like a straw looking bent in a glass of water.
Refraction
These are positively charged particles inside the nucleus that have mass.
Neutrons.
This is a process of a gas cooling down and turning back into a liquid.
whether an object is speeding up or slowing down.
Acceleration
Energy stored in a nucleus of an atom. which can be released through fusion.
Nuclear energy.
Measured in Hertz, this term describes the number of waves pass a point in one second.
Frequency
These are positively charged particles found inside the nucleus to determine the atoms identity.
Protons
This rare phase changes when a solid turns into a gas without melting first.
This measurement describes how fast an object is moving and the exact direction it is traveling.
Velocity
A Fundamental Law states that energy cannot be created or destroyed only changed from one form to another.
Law of conservation of energy.
What makes the human eye able to see?
Visible Light
Pure Substance made entirely of one specific type of atom that cannot be broken down into simpler substances.
Element.
When gas turns directly into a solid skipping the liquid phase.
Deposition
