Which situation is an example of negative acceleration?(1 point)
A bicycle increasing its velocity as the rider pedals harder
A bicycle increasing its velocity as the rider pedals harder
A jogger slowing down at the end of a race
A car moving at a constant velocity
A diver jumping off a diving board and falling to the swimming pool below
A jogger slowing down at the end of a race
The correct answer is: A jogger slowing down at the end of a race.
Negative acceleration occurs when an object is slowing down or decreasing its velocity.
Out of the given options, the situation that represents negative acceleration is when a jogger slows down at the end of a race.
To determine this, you need to understand that acceleration is the rate at which an object's velocity is changing. When an object is experiencing negative acceleration, its velocity is decreasing.
In this situation, the jogger is initially moving at a certain velocity during the race. However, as the jogger approaches the end, they start to slow down, meaning their velocity is decreasing. Therefore, this is an example of negative acceleration.
The other options mentioned, such as the bicycle increasing its velocity and the car moving at a constant velocity, do not represent negative acceleration. The bicycle increasing its velocity is an example of positive acceleration because the rider pedals harder, causing the object to speed up. The car moving at a constant velocity means there is no change in its velocity, so there is no acceleration happening.
