It's a neat piece of science art, and it also tells us something interesting. The arrows show us that the force on the skateboard is constantly changing, both in magnitude as well as in direction. Now the force of gravity obviously isn't changing, so the reason that these force arrows are shrinking and growing and tumbling around is that the skater is changing how their feet pushes and pulls against the board. By applying a variable force that changes both in strength and direction, they're steering the board.

Wider and stronger than the rookies, this model is the perfect size for someone who is better at skating and looking for an upgrade from the rookie models. The pro features a modern concave which allows for not only comfort, but more pop making it easier to learn tricks.
