Newton | unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second |
Newton's 1st law | continues in an existing state of rest or continual motion in the same direction until acted on be external force |
inertia | object's resistance to change in motion |
force | a push or pull exerted on an object |
Newton's 2nd law | sum of the forces is equal to mass of the object multiplied by the object's acceleration |

friction | the resistance to motion that occurs when an object encounters when moving over a surface |
gravity | force the pulls objects toward eachother |
motion | the state at which an object's distance from position is changing |
action force | force exerted by first object on the second object |
reaction force | force exerted by second object in response to first object |
drag | force that acts in the opposite direction as object moving through air |
centripetal force | force that acts on an object in a circular path and is directed to the center |
Newton's 3rd law | as fuel in the rocket ignites, the force of gas expansion and explosion pushes out the back of the rocket and send the rocket skyward |
Newton's 2nd law | as ice skater pushes harder with his leg muscles, he begins to move faster |
Newton's 1st law | when you are standing up in a subway train, and the train suddenly stops, your body continues to go forward |
friction | the blade of an ice skate skimming over the ice results in the production of heat energy causing the ice to melt |
air resistance | sleek shape of bobsled allows greater speeds because of decrease in ____________ |
air resistance | force that is caused by air. The force acts in the opposite direction to an object moving through the air. |
