Kinematic Equations (SUVAT)
These standard equations describe motion under constant acceleration. They relate five variables: $s$ (displacement), $u$ (initial velocity), $v$ (final velocity), $a$ (acceleration), and $t$ (time).
- Velocity-Time:
- Displacement-Time:
- Velocity-Displacement:
- Displacement (Avg Vel):

Formula & Logic
The kinematics equations (SUVAT equations) describe the motion of objects under constant acceleration. They relate displacement, initial velocity, final velocity, acceleration, and time.
Practical Applications
Free Fall Physics
Calculate how fast an object is falling after a certain time (using 9.8 m/s² as acceleration).
Vehicle Performance
Determine the time or distance required for a car to accelerate from 0 to 60 mph.
Braking Distance
Calculate the distance needed for a vehicle to stop given its initial speed and deceleration rate.
Frequently Asked Questions
Q.What does SUVAT stand for?
SUVAT is an acronym for the variables: S (Displacement), U (Initial velocity), V (Final velocity), A (Acceleration), and T (Time).
Q.When can I use these kinematic equations?
These equations are valid ONLY when acceleration is constant (uniform). They cannot be used if acceleration changes over time.
Q.What acceleration should I use for gravity?
On Earth, the standard acceleration due to gravity is approximately 9.8 m/s² (or 32.2 ft/s²), directed downwards.
