Forces
Distortion of Space-Time that draws objects together based on their mass
Gravity
This property of matter resists changes in motion, and is central to Newton's First Law
Inertia
In a game of tug-of-war, both teams pull with equal force and the rope doesn’t move. Newton’s Third Law says the forces are equal, but this determines who actually moves.
Net Force
Energy causes molecules to
move
A valence shell in full when it has
8 electrons
the resistance that one surface or object encounters when moving over another
Friction
According to Newton's First Law, this is required to change the velocity of an object.
Unbalanced Force
A gun recoils backward after firing a bullet. The bullet moves forward, and the gun moves back because of this.
Equal and Opposite forces
1st Law of Thermodynamics
energy and matter can neither be created or destroyed
Stellar nurseries are called
Nebulas
The interaction between positive and negative ions drawing/repelling objects to its electron field.
Electromagnetism
A book remains stationary on a table until this type of force acts upon it
External Force
Two people on skateboards push off each other. One is lighter and moves faster. They both feel the same force, but this causes the lighter one to speed up more.
Having less mass
Mathematical formula that states matter and energy are different states of the same thing
E=MC^2
A supermassive star dies and becomes a
black hole
the force that causes a quark to change into a different type of quark or change a quark's charge
weak nuclear force
Despite no engine thrust, a satellite continues to orbit Earth due to this combination of these two forces
Inertia and Gravity
A rocket flies upward because it pushes gas downward. This is the reaction that makes it move.
the gas pushing back on the rocket
2ND Law of Thermodynamics
Entropy (all interactions wastes energy, tending towards chaos)
Red Giants tend to die in the form of a
Super Nova
force that binds protons and neutrons together
strong nuclear force
A magician pulls a tablecloth out from under a full set of dishes without moving them. This demonstration relies on the dishes' ___ and the magician minimizing ____
Inertia and Friction
In rowing, you push the water backward with your oar. What happens next according to Newton’s Third Law?
the water pushes the boat forward with equal force
Final stage of 2nd law of thermodynamics for the universe
heat death
The outer limit of our solar system is called
Ort cloud
