Displacement calculator processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Precision and calculation record

Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Step-by-step calculation

Inputs are substituted below. Each line evaluates the next operation; intermediate values are displayed to 12 significant digits while the calculation uses full precision.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

Assumes constant acceleration along one axis. A negative result means displacement opposite to the positive axis.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Using Displacement calculator

Displacement = initial velocity × time + ½ × acceleration × time².

Assumes constant acceleration along one axis. A negative result means displacement opposite to the positive axis.

Next: Basic calculator

A worked example

With initial velocity (m/s) = 10, elapsed time (seconds) = 5, constant acceleration (m/s²) = 2, the displacement (m) is 75.

Before you use the result

Assumes constant acceleration along one axis. A negative result means displacement opposite to the positive axis.

Example results for initial velocity (m/s)

These examples use Elapsed time (seconds): 5; Constant acceleration (m/s²): 2. They are reference calculations, not recommended settings.

Initial velocity (m/s)	Displacement (m)
5	50
10	75
20	125
