could someone please explain graphs of motion to me

OpenStudy (anonymous):

graph of velocity againts time shows the velocity of a travelling object, the area represents the displacement graph of distance against time shows the distance travelled by an object, graph of acceleration against time shows the acceleration of a travelling object, the area represents its velocity. basically is how you deal with the units. for example displacement = s distance = m velocity = ms^-1 acceleration = ms^-2

dude thank you sooo much best summary ever

OpenStudy (anonymous):

haha no prob bro

OpenStudy (anonymous):

i just have one question when you are measuring the area would you use cm or the units that you originally drew the graph with

OpenStudy (anonymous):

It'd be the units that you originally drew the graph with. For example, in the velocity graph below, |dw:1339425189158:dw| we can see that the velocity is staying constant at 5 m/s for 2 seconds. Therefore, the area would be\[x = v \times t = (5 m/s)(2 s) = 10 m\]
