Physics Tension/FBD Quiz

tension

specific type of force exerted by a rope or string, symbolized by F of T, mass of object is negligible (ignore it), will sometimes take place of normal force (if straight hanging)

F of T = mg N up

if object hanging on a stationary rope tension will be the weight of the object (same equation as finding weight)

F of T = mg -/+ ma N up

if object on an accelerating rope (if up you add, if down you subtract) the rope's tension will change

F of T = 0

if rope is moving faster than free fall

m = F of T / g +/- a

mass equation

greater normal force

if pushing down on an object on a surface because needs to work against F of g and F of p

F of g = mg

weight equation

smaller normal force

on an inclined plane (F of g is bigger than F of N)
