SUMMARY

The correct formula representing velocity under constant acceleration is V = v0 + at, where v0 is the initial velocity, a is acceleration, and t is time. The formula V = v0 + 2at is incorrect and confuses the integration of acceleration with Galilei's equation v² = v0² + 2ax, which is valid for calculating displacement under constant acceleration. Understanding these distinctions is crucial for accurately solving physics problems related to motion.

PREREQUISITES
  • Understanding of basic kinematics
  • Familiarity with the concepts of velocity and acceleration
  • Knowledge of Galilean physics
  • Ability to perform algebraic manipulations
NEXT STEPS
  • Study the derivation of the equations of motion under constant acceleration
  • Learn about the implications of Galilei's formula v² = v0² + 2ax
  • Explore real-world applications of kinematic equations in physics
  • Practice solving problems involving initial velocity, acceleration, and time
USEFUL FOR

Students of physics, educators teaching kinematics, and anyone looking to deepen their understanding of motion equations in classical mechanics.

which one is correct?

V=v0 + 2at ? or V=v0 + at ?
where v0 is initial and a is acceleration and t is time.
 
Physics news on Phys.org
V=v0 +at

The acceleration part should be common sense. Acceleration * time = velocity.

You're mixing the simple time integration of constant acceleration with Galilei's formula

v^{2}=v_{0}^{2}+2 a x

also valid for constant acceleration along the Ox axis.
