forces Flashcards
a push or a pull one body exerts another
force
an object moving keeps moving at that velocity unless an out side force
newtons first law
the tendency of a object to resist any change in motion
inertia
combination of all forces that act on an object
net force
every object exerts a force on every other object felt as a pull
gravity
the amount of matter or stuff object has
mass
measure of force of gravity on an objects mass
weight
to every action there is an equal (in size) and opposite (in direction) reaction force
newtons third law
mass n the move the force required to stop a moving object
momentum
anything thrown or shot threw the air
projectile
force acting toward the center of a curved or circular path
centripetal force
opposes motion between two surfaces that are touching each other
friction
resists getting an object moving (this is when the object isnt moving)
static friction
resists keeping an object moving (this is when the object is in motion)
kinetic friction
force=mass x acceleration
newtons 2nd law
