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

What Is the SUVAT Calculator?

The SUVAT Calculator is a practical tool that helps you solve kinematic motion problems where acceleration remains constant. It works by applying the standard set of SUVAT equations used in physics and engineering to describe straight-line motion. This tool is useful for students, teachers, engineers, and anyone dealing with motion-related calculations.

SUVAT Equations:
  • \( v = u + at \)
  • \( s = ut + \frac{1}{2}at^2 \)
  • \( v^2 = u^2 + 2as \)
  • \( s = vt - \frac{1}{2}at^2 \)
  • \( s = \frac{1}{2}(u + v)t \)
