Motion in a Straight Line
Compare uniform rectilinear motion (constant velocity) and uniformly accelerated rectilinear motion. Set position, velocity, acceleration and duration, then watch the body move along a straight line.

Simulation
The arrow represents the direction of velocity; its length is proportional to the magnitude (same visual scale for A and B, not a distance scale). The red vector indicates acceleration. Motion is one-dimensional with constant acceleration.
Comparison of Experiments A and B
| Quantity | Experiment A | Experiment B |
|---|
Both bodies are observed at the same instant and share the experiment duration. Dashed purple lines represent B.
Synchronized Graphs
Numbered ticks on the horizontal axis show seconds (including t = 2 s when in range). Click a tick or enter an exact time below. You can also use the arrow keys. On phones, scroll horizontally to read the scales.

Equations and Calculations
Uniformly accelerated motion
x(t) = x₀ + v₀t + ½at²
—
v(t) = v₀ + at

In uniform motion, acceleration is zero. In uniformly accelerated motion, acceleration is constant and may be positive, zero or negative. Negative velocity means motion in the negative axis direction.

Equations and steps update automatically with the simulation parameters.
Calculations use full-precision values; displayed steps are rounded only for readability. The ≈ symbol indicates an approximate numerical value. All added terms have dimensionally compatible units.
