A car moving at a constant speed of 123 km/hr along a straight road is an example of ________.
-
A.
uniform motion
-
B.
rotational motion
-
C.
random motion
-
D.
non-uniform motion
Correct Answer:
A. uniform motion
Explanation:
The correct answer is uniform motion.
A car traveling at a constant speed along a straight path demonstrates uniform motion. This type of movement occurs when an object covers equal distances in equal intervals of time, maintaining both a steady speed and a fixed direction. Because the speed does not fluctuate and the road is straight, the velocity remains constant, distinguishing it from non-uniform, rotational, or random motion.
