Larger (smaller) velocity means
larger (smaller) acceleration.
Two cars are travelling down a road. At 12:15 pm the two drivers
of the cars look at their speedometers. The driver of one car reads
30 mph, the other driver reads 60 mph on their speedometer. Which car
has a greater acceleration? Explain your answer. If you are unable to
determine the answer, explain why you can't.
Students with this misconception will
answer that the car that is travelling at 60 mph has a greater
acceleration since it has a larger velocity.
Related misconceptions/student difficulties that may
arise in the question:
velocity means same acceleration for two objects.
