Uniform acceleration is a type of motion where an object's velocity changes by equal amounts in equal time intervals. This means that the object's acceleration remains constant throughout the motion.
Uniform acceleration is when the acceleration remains constant, while non-uniform acceleration is when the acceleration changes over time. In non-uniform acceleration, the velocity changes by unequal amounts in equal time intervals.
The equations used for solving uniform acceleration problems are the kinematic equations: v = u + at, s = ut + 1/2at^2, v^2 = u^2 + 2as, and s = 1/2(u + v)t. These equations relate the displacement, initial velocity, final velocity, acceleration, and time of an object in uniform acceleration motion.
The direction of acceleration in uniform acceleration is determined by the direction of the change in velocity. If the velocity increases, the acceleration is in the same direction as the motion. If the velocity decreases, the acceleration is in the opposite direction of the motion.
Some real-life examples of uniform acceleration include a car accelerating at a constant rate on a straight road, a free-falling object in a vacuum, and a rollercoaster going down a straight track. These examples demonstrate the constant change in velocity in a specific direction, indicating uniform acceleration.
