01 Uniform Motion
Variables
- sposition
- mmeter
- s₀initial position
- mmeter
- vvelocity
- m/smeters per second
- ttime
- sseconds
Key Formulas
Position
Velocity
Acceleration
Velocity v(t) is the first time derivative of position s(t). A dot above s denotes differentiation with respect to time. For uniform motion, this derivative is constant.
Calculate
Type prefixes directly: 1.5k, 250m or 20u. Results: 3 significant figures.
Position over time. The slope of the line represents velocity.
Constant velocity over time. The signed area under the line represents displacement.
