Newton's Laws
Newtons first law
An object in motion will stay in motion or an object at rest will stay at rest unless acted upon by an unbalanced force Also known as the law of inertia.
Potential Energy
the energy stored in an object or the energy an object has due to its position..
what are atoms
the smallest building block of matter. Made up of positively charged protons, neutrally charged neutrons, and negatively charged electrons.
Fossil fuels
Fossil fuels form from dead plants and animals buried under layers of rock over millions of years, undergoing intense heat and pressure that converts them into energy-rich hydrocarbons
What is a Constant
A factor or condition that stays the same between the control groups and the experimental groups.
Newtons second law
The force an object exerts is equal to its mass times its acceleration F=ma. Objects with more mass will require more force to accelerate.
Waves
a repeating disturbance that carries energy.
Mixture
Formed when two or more substances are physically combined and can be separated by physical means.
Renewable Energy Source
Energy resources that can be reused or replenished. These tend to be better for the environment because they do not release as much pollution or contribute to the greenhouse effect.
Independent Variable
The variable the scientist is able to manipulate(change)
For every action there is an equal and opposite reaction.
What is the Law of Conservation of Energy
energy cannot be created or destroyed on transformed or transferred
Compound
one or more atoms of different elements chemically combined.
Non Renewabe Enery source
Energy resources that are gone once used and not able to be replenished. These tend to be worse for the environment due to releasing of pollution and greenhouse gasses.
Control Group
The group in the experiment that is kept under “normal” conditions, and does NOT receive the variable being tested.
Inertia
An object’s motion will remain the same unless some force changes it.
Nuclear Energy
Energy that is stored in the nucleus of atoms.
Ionic Bond
covalent Bond
A bond that is formed when atoms lose an electron or electrons to other atoms
A bond that is formed when atoms share electrons to fill or stabilize their outer shell.
Green House gas
DEFINITION: Heat trapped in Earth’s atmosphere due to greenhouse gases (Carbon Dioxide, Methane )
what is an experimental group
The group(s) in the experiment that receive the variable being tested.
Net Force
The sum of all forces acting on an object.
Electromagnetic Energy
Energy that travels in waves and can travel through space.
Endothermic reaction
exothermic reaction
A chemical reaction that absorbs(takes in) energy and results in a decrease in temperature.
A chemical reaction that releases energy resulting in an increase in temperature.
What is a carbon footprint
The amount of greenhouse gases released by your everyday actions.
Inverse relationship
When variables move in opposite directions.
