Kinematics Calculator
Kinematics calculator
Solve constant-acceleration motion for final velocity, displacement, and average velocity.
Result
v = 26.6 m/s
s = 189.6 m • v_avg = 15.8 m/s.
Physics signal
Advanced options
Flow
- Enter initial velocity u, acceleration a, and elapsed time t.
- Review final velocity and displacement instantly.
- Use average velocity output for additional consistency checks.
Example
Worked example: u=5 m/s, a=1.8 m/s², t=12 s
- 1 v = u + at = 5 + 1.8×12 = 26.6
- 2 s = ut + 0.5at² = 5×12 + 0.5×1.8×12² = 189.6
- 3 vavg = s/t = 15.8
Final velocity is 26.6 m/s and displacement is 189.6 m.
How
- Enter initial velocity u, acceleration a, and elapsed time t.
- Review final velocity and displacement instantly.
- Use average velocity output for additional consistency checks.
Avoid
- Using non-constant acceleration while applying constant-acceleration equations.
- Entering negative time values.
- Mixing km/h velocities with SI acceleration units without conversion.
Checks
Best fit
Kinematics Calculator is built for solve constant-acceleration motion for final velocity, displacement, and average velocity. If Kinematics Calculator does not match the input scope, compare the answer with a second method.
Input check
Match the entered values to this rule before copying the answer: v = u + at; s = ut + (1/2)at^2; vavg = s/t.
Sanity check
For Kinematics Calculator, use the worked example as a quick benchmark: Final velocity is 26.6 m/s and displacement is 189.6 m. If the kinematics calculator answer is far away, check whether an input, unit, or mode changed.
Before copying
Review this common issue first: using non-constant acceleration while applying constant-acceleration equations.
FAQ
Can acceleration be negative?
Yes. Negative acceleration represents deceleration in the chosen axis direction.
What if time is zero?
Outputs collapse to initial-state values with zero displacement increment.
Does this include drag?
No. The model assumes ideal constant acceleration.
