Which of the following are examples of uniform velocity?
Which of the following are examples of uniform velocity?
The correct option is B Motion of planet around sun
The explanation for correct options
A: Motion of the moon around the earth
As we know, in the case of uniform motion the body covers an equal amount of distance in equal time intervals.
We know that,
- In the case of a satellite, it travels through a path and the gravitational forces of the earth pull it towards the center.
- So, due to which satellite covers equal distance in an equal time span so the motion of the satellite is uniform motion.
B: Motion of planet around the sun
- Similar to option A, the motion of a planet around the sun will be termed a circular accelerated motion.
- However, because there is no change in speed, the magnitude of the speed remains constant (only direction changes). As a result, uniform motion is followed.
The explanation for incorrect options:
C: Motion of car on the crowded road
In a crowded street, a car moves in a zig-zag fashion. It does not travel at a constant rate of acceleration or deceleration. Hence, it follows a non-uniform motion.
D: Motion of a moving fan
The motion of a moving fan is said to be circular motion instead of uniform motion its velocity fluctuates with the fluctuation in the electrical energy.
Hence, options A and B are the correct options.
