Uniform motion is when an object moves at a constant speed in a straight line. This means that the object covers equal distances in equal amounts of time.
Harmonic motion is a type of periodic motion in which an object moves back and forth between two points, passing through a central position and then returning to it again. This type of motion is often seen in oscillating systems such as a pendulum or a spring.
Uniform motion is when an object moves at a constant speed, while accelerated motion is when an object's speed changes over time. In accelerated motion, the object's velocity is changing, either by increasing or decreasing in speed or by changing direction.
Uniform and harmonic motion are both types of periodic motion, meaning they repeat themselves in a regular pattern. Uniform motion is a special case of harmonic motion, where the amplitude (maximum displacement) is constant and the frequency (number of oscillations per unit time) is infinite.
Uniform motion is commonly used in everyday activities such as driving a car at a steady speed or running on a treadmill. Harmonic motion has many practical applications, including timekeeping devices such as pendulum clocks and metronomes, as well as in musical instruments like guitars and pianos.
