Uniform acceleration is the constant rate at which an object's velocity changes over time. This means that the object's speed increases or decreases by the same amount every second.
Uniform acceleration is calculated by dividing the change in velocity by the change in time. This can be represented by the equation a = (vf - vi) / t, where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time.
The main difference between uniform acceleration and non-uniform acceleration is that with uniform acceleration, the rate of change in velocity is constant, while with non-uniform acceleration, it is changing. This means that the object's speed is either increasing or decreasing at a varying rate.
Some common examples of uniform acceleration include a car traveling at a constant speed on a straight road, an object falling due to gravity, and a pendulum swinging back and forth.
Uniform acceleration is related to Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that a constant force will result in a constant acceleration, which is uniform acceleration.
