The Equations of Motion Solver (also called SUVAT Solver) is an interactive online tool that helps you quickly solve problems involving constant acceleration (uniformly accelerated motion) in physics.

It uses the four main equations of motion (often called SUVAT equations):

1. v = u + at
2. s = ut + ½at²
3. v² = u² + 2as
4. s = (u + v)t / 2

Where:

• u = initial velocity (m/s)
• v = final velocity (m/s)
• a = acceleration (m/s²)
• t = time (s)
• s = displacement (m)

Instead of choosing which equation to use and rearranging it yourself, you simply enter any 3 or more known values, click “Calculate”, and the tool automatically finds the missing ones using the appropriate equations.

How to Use It

1. Enter known values Fill in at least 3 of the five boxes:
   • Initial velocity (u)
   • Final velocity (v)
   • Acceleration (a)
   • Time (t)
   • Displacement (s)
   Leave the unknown ones blank.
2. Click “Calculate Missing Values” The tool will compute and fill in the missing values instantly.
3. View the results All five values (u, v, a, t, s) will be displayed below with units.
4. Click “Reset” to clear everything and start a new problem.

Example:

• Enter: u = 0 m/s, a = 9.8 m/s², t = 5 s
• Click Calculate
• Result: v ≈ 49 m/s, s ≈ 122.5 m (This is an object falling freely under gravity for 5 seconds.)

The tool works on phones, tablets, and computers (fully responsive).

Who Can Use It?

Anyone studying or working with basic mechanics can benefit from it, including:

• High school students (Grades 9–12) learning kinematics/physics.
• College/university students in introductory physics or engineering courses.
• Teachers — for quickly checking answers or preparing examples.
• Exam preparers (e.g., GCSE, A-Level, AP Physics, SAT Physics, JEE, NEET).
• Hobbyists or self-learners interested in physics problems.
• Engineers needing quick calculations for simple motion problems.
