Equations
Displacement-time relation (constant acceleration)
Kinematics · id kin_x_at
x = v_0 t + \frac{1}{2} a t^2
| Symbol | Quantity | Unit | Meaning | Usual range |
|---|---|---|---|---|
x | displacement | m | Displacement after time t | 0 to 100000 |
v0 | initial velocity | m/s | Velocity at t = 0 | 0 to 1000 |
a | acceleration | m/s^2 | Constant acceleration | 0 to 100 |
t | time | s | Elapsed time | 0 to 10000 |
Assumptions
- Acceleration is constant
- Motion is along a straight line
- Starts at x = 0
Valid when
- Speeds far below the speed of light
