Which of the following is an example of negative acceleration?

Question

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

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, as the car approaches the stoplight and reduces its speed, it is experiencing negative acceleration.
