Which situation is an example of negative acceleration?(1 point) Responses A bicycle increasing its velocity as the rider pedals harder A bicycle increasing its velocity as the rider pedals harder A car moving at a constant velocity A car moving at a constant velocity A diver jumping off a diving board and falling to the swimming pool below A diver jumping off a diving board and falling to the swimming pool below A jogger slowing down at the end of a race
A jogger slowing down at the end of a race
The correct answer is: A jogger slowing down at the end of a race.
To determine which situation is an example of negative acceleration, we need to understand the concept of acceleration first. Acceleration refers to a change in velocity over time.
In the given options, acceleration would be considered negative if the object is slowing down or decreasing its velocity.
Option A: A bicycle increasing its velocity as the rider pedals harder is an example of positive acceleration because the velocity is increasing.
Option B: A car moving at a constant velocity would have zero acceleration because there is no change in velocity.
Option C: A diver jumping off a diving board and falling to the swimming pool below is an example of negative acceleration because the diver's velocity is decreasing due to gravity.
Option D: A jogger slowing down at the end of a race is also an example of negative acceleration because the jogger's velocity is decreasing.
Therefore, the situation that represents negative acceleration is option D, where the jogger is slowing down at the end of the race.
