distance and velocity time graphs Flashcards
on a distance time graph what does a straight line show?
an object at rest
a diagonal line with a less steep gradient shows what on a distance time graph?
constant speed
what does a diagonal line with a steeper gradient show on a distance time graph?
faster constant speed
what does a diagonal line with a not very steep gradient show on a distance time graph?
slower constant speed
how to figure out distance from a velocity time graph?
area under graph
what does a straight line on a velocity time graph show?
constant speed
what goes on the x axis in both distance time graphs and velocity time graphs?
time
what is the definition of velocity?
change in distance per unit time
what is the definition of acceleration?
rate of change of velocity
what is the formula for acceleration?
A= v-u/t
