# forces vocab :)

momentum the amont of matter in somthing the pruduct of an objects mass and it volocity centriptal force
formula for monmentum the force that is pulling an object in circular motion towerdas the center of the circle m= pvgeosynchronous orbit
law of conversation of momentum the toltal momentum of any group of objects remains the same unless outside forces also act on the objects
force a push or a pull that gives energy to an object
unit of force forces are mesured in newtons N
net force the total of all forces acting on an object
inertia the tendency of matter to resist a change in its motion
balanced forces the net force acting on an object is zero
unbalanced forces the net force acting on an object is not zero
magnitude the amount of a mesurement
friction a force that one suface exerts on another when the two surfaces are in contact with each other
static friction friction between non-moving objects
kinetic friction friction between moving objects
sliding friction friction between objects that slide against each other
rolling friction occures when an object rolls a surface
fluid friction occurs when an object moves through a fluid or a gas
newtons first law of motion objects at rest will stay at rest & objects in motion will stay in motion at a constant velocity unles acteds on by an unbalanced force
netons second law of motion the net force acting on an object is equal to the product of the objects mass and acceleration
newtons third law of motion for every acting force there is a reaction force that is equal , but acts in the oppisite direction
law of universal gravition all objects in the universe are attracted to each other strenths of attraction depends on the objects masses and distance from each other
freefall the motiong of an object when gravity is the only force acting on it
terminal veloity greatest velocity of a falling object occures when the force of gravity is equal to the force friction
weight a measure of he force of gravity on an object
geoynchronous orbit occurs when the an object orbits another object at a rate equal to the 2nd objects rate of rotation
