Snowball fights are a favorite for the cold weather. Many people complain through because they can't throw it or it'd be a weak attempt. Understanding physics could change that for many. For starters, you would want a 45 degree angle giving you the maximum distance possible. This was explained during the projectile unit earlier in the year. You must also follow through afterwards in order to give it as much force as you can. The greater the force applied can leave you to a better fight because it will help the ball fly. Plus, the follow through allows you greater contact with the ball which creates the force.
