Equations of Motion in a Straight Line

For uniformly accelerated motion in a straight line, there are three important equations of motion:

1. v = u + at
   Where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
2. s = ut + ½at²
   Where s is the displacement, u is the initial velocity, a is the acceleration, and t is the time.
3. v² = u² + 2as
   Where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement.

These equations are derived from the definitions of velocity and acceleration and can be used to solve various problems involving motion in a straight line.
