Big concepts Flashcards
What are the three fundamental forces?
S,W,G
Strong Nuclear, Weak Nuclear, Gravity
What are the four the main ideas of physical science?
S+T, M+C, F+M, E
Space and Time, Matter and Change, Forces and Motion, Energy
It can be said that the universe is composed of Space, Time, Matter, Energy, and Space
What does the first law of thermodynamics state?
Energy
Energy cannot be created or destroyed it only changes form.
What does the second law of thermodynamics state?
Energy, or Systems
Systems go from order to disorder.
Energy can flow from cold objects to warmer objects only if work is done on the system.
What does the third law of thermodynamics state?
Absolute
Absolute zero cannot be reached.
Bigger differences in temperature become increasingly harder to achieve.
What does the law of conservation of momentum state?
If no
If no net forces act on a system, then the total momentum does not change.
What are four states of matter?
S, L, G, P
Solid-Definite shape and volume. Liquid-Definite volume but not shape. Gas-No definite volume or shape. Plasma-Electron leave nucleus. Less well know BEC-Acts as a solid.
What is Newton’s first law of motion.
An object
An object at rest will stay at rest, and an object in motion will stay in motion unless a force acts upon it.
What is the second law of motion.
Force equals
Force equals mass time acceleration.
You need a force to change the movement of an object.
What is the third law of motion?
For every
For every action their is an equal and opposite reaction.
What is the law of conservation of matter (mass)?
Matter
Matter cannot be created or destroyed it only changes form.
What does the law of conservation of energy and mass state?
Energy equals
E=mc2
Explains that mass and energy can be changed back and forth.
What do opposite charges do to each other?
Attract
What do like charges do?
Repel
What are the six character expectations for class?
C, H, R, C, R, T
Caring, Citizenship, Honesty, Respect, Responsibility, Trustworthiness
