Question

how can you find the total displacement during the time interval of a graph?

please help totally lost :/

anonymous · Answer

the total displacement will be equal to the area under the curve. or in other words, it is the integral of the equation.

make sense?

if there is an equation I can help you more..

@DemolisionWolf is correct IF the graph is showing velocity vs time. 

Recall our calculus based expressions of velocity and acceleration. $$v = {dx \over dt} ~~ {\rm and} ~~ a = {dv \over dt} = {d^2 x \over dt^2}$$

If the graph shows acceleration vs time, we need to take the interval twice.
