Work and Power — Quiz

Question 6 • Physics

Which statement about work and power correctly describes an automobile race?

Answer
A
The car that finishes last has the lowest power.
B
The cars do different amounts of work depending on how fast they finish.
C
The car with the greatest power travels the greatest distance.
D
The cars do different amounts of work depending on their power.

Explanation

In the same race, the cars cover the same distance, so finishing last means taking the most time. Power is the rate of doing work: for the same amount of work, taking longer means having lower average power. Thus, the car that finishes last has the lowest power; power does not determine how much work is done or how far the cars travel in this race.
