Motion equation solver
Solve one missing motion quantity with consistent SI units.
How this works
Constant-speed relation: distance = speed × time.
Example
Using the example inputs, speed is 10 m/s.
- Quantity to solve
- Speed
- Distance (ignored when solving distance)
- 100 m
- Time (ignored when solving time)
- 10 s
- Speed (ignored when solving speed)
- 5 m/s
- Speed
- 10 m/s
Scope and assumptions
Uniform average speed only; unused fields are ignored in the equation.
