Studied by 46 peopleInertia
matter it it's state of rest/motion, unless changed by an external force
Friction
Tension between 2 things
Mass
quantitive measure of inertia/fundamental property of matter
Natural motion
objects moving naturally / ex: wind, a rock falling, etc...
Violent motion
requires external force / ex: pushing a mass
Scalers
quantities described by magnitude
vectors
quantity that has both magnitude and direction
mechanical equilibrium
a state where the sum of all forces acting on an object of interest is zero
force of tension
pulling on some sort of rope or string, always hanging from above / hanging from something
force of gravity
same thing as force of weight
normal force
support force
applied force
doesn't matter what direction, applying force to an object to make it move.
static equilibrium
when an object is at rest
dynamic equilibrium
when an object is in motion
aristotle
he found natural and violent motion
copernicus
he found that the sun was the center of the universe, but didn't share bc he didn't want to get executed
galileo
demolished aristotle's assertions in the 1500's. he found different objects of different weight fall to the ground at the same rate in the absence of air resistance.
newton
he created inertia, found that objects naturally want to stay at rest already if in rest and motion already if in motion
