A stopwatch measures short intervals of time, useful in experiments and sports.
Distance measures the total path traveled by an object, regardless of direction, while displacement measures the shortest straight-line distance between the initial and final positions, considering direction. Distance is scalar, and displacement is vector.
A proper reference point in motion is important because it allows us to accurately determine and describe the position, distance, and direction of an object’s movement, ensuring clear and consistent measurement of its motion.
Oscillatory motion is back-and-forth movement around a central position, like a pendulum.
