Sharp
Slow Shutter Speed
This worked well for these photos because I wanted to show the movement of the water being splashed out of the glass and the ball being pushed forward. From both photos you can see movement.
Fast Shutter Speed
For these photos this worked well because It was sunny outside and I wanted the moment to stop. You can see in the water one, the splash is very sharp and at the exact moment. In the flower one the wind was blowing but with the fast shutter speed I was able to capture the flowers with an exact position. no movement.
