Explanation:Uniform motion is the kind of motion in which a body covers equal displacement in equal intervals of time. It does not matter how small the time intervals are, as long as the displacements covered are equal.
If a body is involved in rectilinear motion and the motion is uniform, then the acceleration of the body must be zero.

Uniform Motion in a Straight Line
Uniform motion in a straight line refers to the motion of an object where its displacement remains constant in equal intervals of time. In other words, the object covers equal distances in equal intervals of time. This type of motion is characterized by a constant velocity.
Explanation:
To understand why option C is the correct answer, let's consider the different options one by one.
a) If the displacement of an object is decreasing in equal intervals of time, it implies that the object is moving in the opposite direction. This is not an example of uniform motion in a straight line.
b) If the displacement of an object is increasing in equal intervals of time, it implies that the object is accelerating. This is also not an example of uniform motion in a straight line.
c) If the displacement of an object is equal in equal intervals of time, it implies that the object is covering the same distance in the same amount of time. This is the characteristic of uniform motion in a straight line.
d) If the displacement of an object is equal but in not equal intervals of time, it means that the object is not covering the same distance in each interval of time. This is also not an example of uniform motion in a straight line.
Therefore, the correct answer is option C, where the displacement of the object is equal in equal intervals of time.
Key Points:
- Uniform motion in a straight line refers to the motion of an object where its displacement remains constant in equal intervals of time.
- The object covers equal distances in equal intervals of time.
- This type of motion is characterized by a constant velocity.
- If the displacement of an object is decreasing, increasing in equal intervals, or equal in not equal intervals of time, it is not an example of uniform motion in a straight line.
