force vocab Flashcards
a push or pull one body exerts on another
force
an object moving at a constant velocity kept moving at that velocity an abject at that rest stays at rest unless acted upon by a net force
newtons 1st law
the tendency of an object to resist any change in motion
inersia
combo of all forces that act on an object
net force
every object exerts a force on every other object
gravity
amount of matter an object has (measured in kilograms)
mass
measure of force gravity’s of an objects mass
weight
net force acting on an object causes the object to accelerate (F=MA= Force=Mass X Acceleration)
2nd law
opposes motion between two surfaces that are touching each other
friction
resists an object movement(this is when an object is not moving)
static friction
sliding/rolling friction
kinetic friction
to every action there is an equal (in size) & opposite (in direction) reaction force
3rd law
anything that is thrown or shot into the air
projectille
force acts toward the center of a curved or circular path
centennial force
mass on the move the force required to stop a moving object
momentum
