SUVAT Calculator — Solve for s, u, v, a, t

SUVAT Calculator

SUVAT Calculator — enter any three known values (s, u, v, a, t) to instantly compute the rest with units, step-by-step formulas, and a live v–t graph.

What is the SUVAT Calculator?

The SUVAT Calculator is a powerful tool for solving kinematics problems involving uniformly accelerated motion. SUVAT stands for the five key variables in these equations: displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). This SUVAT Calculator helps students, teachers, and professionals quickly solve for any unknown variable when at least three values are known.

Using the SUVAT equations, this calculator can handle various unit systems and automatically converts between them, making it versatile for different applications. Whether you're working on physics homework, engineering problems, or scientific research, this SUVAT Calculator provides accurate results with detailed step-by-step solutions.

SUVAT Equations (Plain Text Formulas)

The SUVAT equations are five fundamental equations that describe motion with constant acceleration:

v = u + a * t
s = (u + v) / 2 * t
s = u * t + 0.5 * a * t^2
s = v * t - 0.5 * a * t^2
v^2 = u^2 + 2 * a * s

How to Use the SUVAT Calculator

Using our SUVAT Calculator is straightforward:

  1. Identify three known variables from your problem (s, u, v, a, t)
  2. Enter these values in the corresponding input fields
  3. Select the appropriate units for each value
  4. Leave the unknown variables blank
  5. Click the "Calculate" button
  6. The calculator will compute the missing values and display the results
  7. View the step-by-step solution to understand the calculation process
  8. Examine the velocity-time graph for visual understanding

The SUVAT Calculator automatically detects which equations to use based on the provided values. It handles unit conversions seamlessly and provides results in multiple units for convenience.

Worked Examples

Example 1: Finding Final Velocity

Problem: A car accelerates from 20 m/s at 4 m/s² for 10 seconds. What is its final velocity?

Solution using SUVAT Calculator:

  1. Known values: u = 20 m/s, a = 4 m/s², t = 10 s
  2. Enter these values in the calculator
  3. The calculator uses the equation: v = u + a * t
  4. Substitution: v = 20 + 4 * 10
  5. Calculation: v = 20 + 40 = 60 m/s

Answer: The final velocity is 60 m/s.

Example 2: Finding Displacement

Problem: An object starts from rest and accelerates at 5 m/s² for 8 seconds. How far does it travel?

Solution using SUVAT Calculator:

  1. Known values: u = 0 m/s, a = 5 m/s², t = 8 s
  2. Enter these values in the calculator
  3. The calculator uses the equation: s = u * t + 0.5 * a * t^2
  4. Substitution: s = 0 * 8 + 0.5 * 5 * 8^2
  5. Calculation: s = 0 + 0.5 * 5 * 64 = 160 m

Answer: The displacement is 160 meters.

FAQs

What does SUVAT mean?

SUVAT stands for displacement (s), initial velocity (u), final velocity (v), acceleration (a) and time (t); it describes motion under constant acceleration.

How many values do I need to solve SUVAT?

At least three known variables are required to compute the others using the SUVAT equations.

Can the calculator handle different units?

Yes — the tool auto-converts commonly used units and shows converted values.

What are the assumptions of SUVAT equations?

The SUVAT equations assume constant acceleration and motion in a straight line. They do not account for variable acceleration, circular motion, or relativistic effects.

Can I use SUVAT for vertical motion?

Yes, SUVAT equations can be applied to vertical motion under constant acceleration, such as free fall where a = g (approximately 9.8 m/s² downward).
