Which of the following is an example of uniform motion?A The motion of...
Satellites revolve around their planets in almost circular orbits with constant speed. Thus, during their motion, the speed remains constant, while the direction of motion changes continuously. As a result, there is a change in their velocity. Moon moves in uniform circular motion around the earth. It is the force of gravity of the earth which keeps the moon in circular orbit around it. The motion of any particle on the arm of a clock is circular as thus uniform motion.

Which of the following is an example of uniform motion?A The motion of...
The correct answer is (b) (b), (c), and (d) are correct.
Explanation:
Uniform motion refers to the motion of an object in which its speed remains constant over time. In other words, an object in uniform motion covers equal distances in equal intervals of time. Let's analyze each option to identify examples of uniform motion:
A) The motion of a car in a busy road: This is not an example of uniform motion. In a busy road, a car may have to stop, slow down, or speed up due to traffic conditions, traffic lights, or other obstacles. Therefore, the speed of the car is not constant, and it does not cover equal distances in equal intervals of time.
B) The motion of a satellite around the planet: This is an example of uniform motion. Once a satellite is launched into orbit around a planet, it experiences a gravitational force that keeps it in a stable orbit. The satellite follows a circular path at a constant speed, covering equal distances in equal intervals of time.
C) The motion of the moon around the Earth: This is also an example of uniform motion. The moon orbits around the Earth in an elliptical path at a constant speed. Although the speed varies slightly due to the gravitational interactions with the Earth and other celestial bodies, it can be considered uniform motion over short periods of time.
D) The motion of any particle on the arm of a clock: This is another example of uniform motion. The particles on the arm of a clock move in a circular path at a constant speed. The hour hand, minute hand, and second hand of a clock all exhibit uniform motion as they cover equal distances in equal intervals of time.
Therefore, options (b), (c), and (d) are correct examples of uniform motion.
