- Uniform Motion means Body covers equal distance in an equal time interval,
- A satellite goes around the earth in a circular orbit with constant speed and covers equal distances in equal time intervals.
- The arms of the clock cover the equal distance in every hour,
- The moon revolves around the earth and takes equal time for every revolution.
- The motion of the car on a busy road is not an example of a uniform motion.

Uniform motion refers to the motion of an object in which it covers equal distances in equal intervals of time. In other words, the object moves at a constant speed in a straight line. Let's analyze each option to determine which one represents uniform motion.
(A) The motion of the car on a busy road:
- The motion of a car on a busy road is not necessarily an example of uniform motion. Cars typically accelerate, decelerate, and change their speed frequently due to traffic conditions, traffic lights, and other factors. Therefore, the motion of a car on a busy road does not represent uniform motion.
(B) The motion of a satellite around the planet:
- The motion of a satellite around the planet can be considered an example of uniform motion. Satellites are designed to orbit the Earth at a constant speed, maintaining a consistent distance from the planet. The gravitational force acting on the satellite keeps it in a stable orbit, resulting in uniform motion.
(C) The motion of the moon around the Earth:
- The motion of the moon around the Earth is also an example of uniform motion. The moon follows an elliptical orbit around the Earth, with its speed remaining relatively constant. Although the moon's distance from the Earth varies slightly due to its elliptical path, its motion is considered uniform over short time intervals.
(D) The motion of any particle on the arm of a clock:
- The motion of any particle on the arm of a clock represents uniform motion. The minute hand, hour hand, and second hand of a clock move at a constant speed, completing one revolution in a specific time period. Therefore, the motion of particles on the arms of a clock is uniform.
Based on the analysis, options (B), (C), and (D) represent examples of uniform motion. Therefore, the correct answer is option (D) - "All of these."
