Angles: What's Good


Content Source:

Type: Audio/Video


Take the court with retired NBA star and current basketball analyst Kendall Gill to learn about the science of the perfect shot. We use angles every day—to build ramps and slides, steer a car, shoot basketballs, throw baseballs, and kick soccer balls. In fact, the science of angles is in almost every sport we play and every movement we make, so go out and play a game with your kids.
