A car covers a distance of 10 km in the first 15 minutes, 10 km in the next 20 minutes, and 10 km in the following 25 minutes. What type of motion is the car exhibiting?
Options
Option A
Uniform motion
Option B is correct
Non-uniform motion
Option C
Oscillatory motion
Option D
Periodic motion
Explanation
Uniform motion occurs when an object covers equal distances in equal intervals of time. In this scenario, the car covers equal distances (10 km) but in unequal time intervals (15 minutes, 20 minutes, 25 minutes). Therefore, the car is exhibiting non-uniform motion. Oscillatory motion involves a to-and-fro movement, and periodic motion repeats itself after regular intervals, neither of which describes this situation.
