Following notations / inferences (right side) may be written / considered when you read the lines below (left side)
Uniform linear motion a=0
started from rest u=0
comes to rest v=0
stopped v=0
pentrated through distance x and stopped v=0
straight line and unidirectional speed=velocity (magnitude)
vertically upward motion u and g opposite sign
vertically downward motion u and g same sign
higher slope of x-t graph higher velocity
displacement in 5th second dispacement in 5 second - displacement in 4 second
constant velocity graph between v & t will be a line paralled to time axis.
Area under v-t graph Displacement as x=vt
