Here I test the effects of changing the shutter and aperture of the camera simulator on exposure and motion blur. For this text I kept the ISO at 1600 as a control. Also Increasing the ISO too much can effect the noise of the image.

High aperture (f-22) with normal shutter speed (1/60) – underexposed:

Low aperture (f-2) with normal shutter speed (1/60) – overexposed

Notice how the background is blurred because the aperture is large (low f stop) meaning lots of light can enter the sensor, but its less focused.

Medium aperture (f-9.5) with medium shutter speed (1/60) – good exposure

Medium aperture (f-9.5) with a low shutter speed (1/8) – overexposed

Medium aperture (f-9.5) with a high shutter speed (1/1500) -underexposed

Notice how the propeller how little motion blur, that is because the sensor is only open for a short amount of time. This means it captures less light but fast moving object will have less motion blur.
