Displacement Calculator

Use this displacement calculator to find the change in position of an object. It lets you calculate displacement under various conditions of motion using different formulas:

If the displacement is based on average velocity (v) over a constant time (t):

S = v × t

If the displacement involves initial velocity (u) and constant acceleration (a) over time (t):

S = u t + ½ a t²

If the displacement assumes constant acceleration with initial and final velocities (u and v) over time (t):

S = ½ (v + u) t

What is Displacement?

"Displacement is the shortest distance an object travels in a straight line from its starting point to its ending point."

It represents the change in position of an object, considering both magnitude and direction.

Quantity: Vector
SI Unit: meter (m)

Example: A car moves 20 meters east, then 10 meters west. The total distance traveled is 30 meters (20 + 10), but the displacement is 10 meters east, as this is the net change in position.

Displacement of an object

How to Calculate Displacement

Example 1:

If a car moves with an average velocity of 40 m/s for 120 s, the displacement is:

S = v × t = 40 × 120 = 4800 m

Example 2:

A body starts from rest and reaches a velocity of 80 m/s after 30 s. Assuming constant acceleration:

Initial velocity u = 0 m/s
Final velocity v = 80 m/s
Time t = 30 s

S = ½ (v + u) t = ½ (80 + 0) × 30 = 1200 m

Example 3:

A car has an initial velocity of 20 m/s and acceleration 2 m/s² for 15 s. Find displacement:

Initial velocity u = 20 m/s
Acceleration a = 2 m/s²
Time t = 15 s

S = u t + ½ a t² = 20 × 15 + ½ × 2 × 15² = 300 + 225 = 525 m

Difference Between Displacement & Distance

Feature	Distance	Displacement
Definition	Total length of the path traveled	Straight-line path from start to end
Direction	No	Yes
Quantity	Scalar	Vector
Possible values	Always positive or zero	Positive, negative, or zero
Path dependence	Depends on actual path	Independent of path
Measurement	Along any path	Straight line from start to end
Example	Car drives a curvy route for 10 km	Person walks 4 steps east, then 4 steps west → displacement 0 km
