A car moving at a constant speed of 123 km/hr along a straight road is an example of ________.
-
A.
non-uniform motion
-
B.
uniform motion
-
C.
random motion
-
D.
rotational motion
Correct Answer:
B. uniform motion
Explanation:
When an object travels in a straight line at a constant speed, it covers equal distances in equal intervals of time, regardless of how small those intervals are. This type of movement is defined as uniform motion because the velocity remains unchanged throughout the journey. Since the car maintains a steady speed of 123 km/hr without changing direction, it serves as a perfect example of uniform motion.
