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?
