About SUVAT Kinematics

SUVAT equations are a set of formulas used in kinematics to describe the motion of objects under constant acceleration. The variables represent:

  • S: Displacement (position change)
  • U: Initial velocity
  • V: Final velocity
  • A: Constant acceleration
  • T: Time interval
The Five SUVAT Equations
  1. v = u + at
    Final velocity equals initial velocity plus acceleration multiplied by time.
  2. s = ut + ½at²
    Displacement equals initial velocity multiplied by time plus half of acceleration multiplied by time squared.
  3. v² = u² + 2as
    Final velocity squared equals initial velocity squared plus two times acceleration multiplied by displacement.
  4. s = vt - ½at²
    Displacement equals final velocity multiplied by time minus half of acceleration multiplied by time squared.
  5. s = ½(u + v)t
    Displacement equals half of the sum of initial and final velocities multiplied by time.
Applications of SUVAT Equations

These equations are used in various fields including:

  • Physics: Analyzing particle motion, projectile trajectories
  • Engineering: Designing vehicles, elevators, and machines
  • Sports Science: Analyzing athlete performance, ball trajectories
  • Automotive Industry: Vehicle acceleration and braking calculations
  • Aerospace: Rocket launching and aircraft landing calculations
Limitations

SUVAT equations only apply when:

  • Acceleration is constant throughout the motion
  • Motion is in a straight line (one-dimensional)
  • There is no air resistance or other external forces changing the acceleration

Understanding the SUVAT Calculator

The SUVAT Calculator helps you work out important kinematic values. These values include things like initial and final velocity, acceleration, time, and displacement. These factors are vital when studying motion, especially when the acceleration is constant. By using this calculator, you can quickly find unknown variables when you have some known values.

How the Calculator Works

This calculator utilizes the SUVAT equations, which are a collection of five formulas used in Physics. These equations relate displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). To get results, you only need to enter at least three of these five values, and the calculator will do the rest. It works seamlessly to give you accurate results.
