Which of the following is an example of negative acceleration?

Question

a
a runner speeds up at the end of a race
b
a car slowing down at a stoplight
c
a car going at a constant velocity down a highway
d
a car speeding up after leaving a stoplight

Answer 1

The correct answer is:

b. a car slowing down at a stoplight

Negative acceleration, also known as deceleration, occurs when an object is slowing down. In this case, the car is decreasing its speed as it approaches the stoplight.
