Two objects, Object P and Object Q, move along a straight road. Object P travels 20 meters every 2 seconds, while Object Q covers 20 meters in the first 2 seconds and 30 meters in the next 2 seconds. Which statement is correct about their motions?
Object P is in uniform motion, while Object Q is in non-uniform motion.
Object P covers equal 20 m distances in equal 2 s intervals, so it moves uniformly; Object Q covers different distances (20 m, then 30 m) in equal time intervals, so its motion is non-uniform. Hence, the correct answer is Object P is in uniform motion, while Object Q is in non-uniform motion.
