Question	Answer
force	is a push or a pull that acts on an object.
net force	is the overall force acting on an object after all the forces are combined
newton	is the force that causes a 1-kilogram mass to accelerate at a rate of 1 meter per second each second (1 m/s2).
balanced force	the net force is zero and there is no change in the objects motion
friction	force that opposes the motion of an object that touch as they move past each other
static friction	the friction force that acts on objects that are not moving
sliding friction	a force that opposes the direction of motion of an object as it slides over a surface
rolling friction	a friction force that acts on rolling objects
fluid friction	the motion of an object through a fluid
air resistance	fluid friction acting on an object moving through the air
gravity	the force that acts between any two masses
terminal velocity	the constant velocity of a falling object when the force of air resistance equals the force of gravity
projectile motion	the motion of a falling object after it is given an initial forward velocity
inertia	the tendency of an object to resist change in its motion
mass	the measure of the inertia of an object depends on the amount of matter an object contains
acceleration	net force /mass
weight	the force of gravity acting on an object
"Weight Equals"	mass x acceleration due to gravity
momentum	the product of an objects mass and its velocity
momentum formula	mass x velocity
law of conservation of momentum	no net force acts on a system than the total momentum of the system does not change
electromagnetic force	associtated with charged particles
strong nuclear force	a powerful force of attraction that acts only on the neutons and protons in the nucleus, holding them together
weak nuclear force	an attraction force that only acts over a short range
gravitational force	an attraction force that acts between any two masses
centripetal force	a center directed force that continuously changes the direction of an object to make it move in a circe
