Question

An object moves from position x = -1.88 m to x = -4.27 m. What was its displacement? (Unit = m)

Answer 1

Displacement is change in the position of object

so we can define it as

$d = x_f - x_i$

$x_f = - 4.27 m$

$x_i = -1.88 m$

now displacement is given as

$d = -4.27 - (-1.88) = -2.39 m$

so it will displace by 2.39 m in negative direction
