The SLR, shutter, and lense

If I was about to shoot a sprint at a track meet, and my shutter speed was set at 60, I would increase the shutter speed because faster shutter speeds are used for high light, and it stops action
If I was shooting outside on a bright sunny day, and I wanted to make sure that I get as much stuff in focus as possible i would use the F-16 because the longer the depth of field, the more everything will be in focus.
