Forces/ Acceleration

air resistance The fluid FRICTION experienced by objects FALLING THROUGH AIR.
balanced forces EQUAL FORCES acting on an object in opposite directions.
centripetal force A FORCE that causes an object to MOVE IN A CIRCLE.
fluid friction FRICTION that occurs as an object moves THROUGH A FLUID.
force A push or pull exerted on an object.
free fall The motion of a FALLING OBJECT when the only force acting on it is GRAVITY.
friction A force that one surface exerts on another when the two RUB AGAINST EACH OTHER.
gravity The force that pulls objects towards each other.
inertia Tendency of a moving object to CONTINUE IN A STRAIGHT LINE or a stationary object to REMAIN IN PLACE.
law of conservation of momentum THe RULE that the TOTAL MOMENTUM of objects in an interaction DOES NOT CHANGE.
momentum The PRODUCT of an object's MASS and VELOCITY.
net force The OVERALL FORCE on an object when all the individual forces acting on an object are added together.
newton A UNIT OF MEASURE that equals the FORCE required to accelerate one kg of mass at a rate of 1 m/s/s.
projectile An object that is thrown.
rolling friction FRICTION that occurs when an object ROLLS over a surface.
sliding friction FRICTION that occurs when one solid surface SLIDES OVER another.
terminal velocity MAXIMUM VELOCITY a falling object achieves.
unbalanced forces A NONZERO NET FORCE that changes an object's motion.
