Uniform Translatory Motion
In uniform translatory motion, all parts of an object move with the same velocity (both magnitude and direction), and this velocity remains constant throughout the motion. The correct answer to the given question is option 'C', which states that all parts of the ball have the same velocity, and this velocity is constant.
Explanation:
To understand why option 'C' is the correct answer, let's analyze the other options:
a) It is at rest:
If the ball is at rest, then it is not in motion. In uniform translatory motion, the object is moving with a constant velocity, so option 'a' is incorrect.
b) The path can be a straight line or circular and the ball travels with uniform speed:
While it is true that the path can be a straight line or circular in uniform translatory motion, the important distinction here is that the ball should travel with a constant velocity. Uniform speed implies that the magnitude of velocity remains constant, but the direction can change. In uniform translatory motion, both the magnitude and direction of velocity remain constant, so option 'b' is incorrect.
c) All parts of the ball have the same velocity (magnitude and direction) and the velocity is constant:
This option accurately describes the characteristics of uniform translatory motion. In such motion, all parts of the object have the same velocity, meaning that their speeds and directions are identical. Additionally, this velocity remains constant throughout the motion. Therefore, option 'c' is the correct answer.
d) The center of the ball moves with constant velocity and the ball spins about its center uniformly:
This option describes a combination of translatory and rotational motion. In uniform translatory motion, there is no rotation or spinning involved. The entire object moves as a whole, and all parts have the same velocity. Therefore, option 'd' is incorrect for the given question.
To summarize, in uniform translatory motion, all parts of the object have the same velocity (magnitude and direction), and this velocity remains constant throughout the motion. Therefore, the correct answer is option 'c'.
