Models Flashcards
particle model
dimensions of the objects are negligible
rod model
all dimensions but one are negligible, like a pole or beam
lamina model
object with area but negligible thickness, like a sheet of paper
uniform body model
mass is distributed evenly
light object model
mass of the object is small compared to other masses, like a string or a pulley
inextensible string
a string that does not stretch under load
smooth surface model
self explanatory
rough surface model
if a surface is not smooth, it is rough
wire model
rigid thin length of metal
pulley model
all pulleys you consider will be smooth and light
bead model
particle with a hole in it, for threading on a wire or string
peg model

resistance is experience as an object moves through the air
gravity model
