A skateboard is moved by pushing with one foot while the other remains on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy;" if the rider's leading foot is their left foot, they are said to ride "regular." If the rider is normally regular but chooses to ride goofy, they are said to be riding in "switch," and vice versa. A skater is typically more comfortable pushing with their back foot; choosing to push with the front foot is commonly referred to as riding "mongo", and has negative connotations of style and effectiveness in the skateboarding community.
One foot on the tail, (by foot I mean the ball of the foot which is just behind the big toe) the other foot is about an inch behind the bolts(screws) for the front truck. Basically, the back foot quickly pushes the tail down, and right when the tail of the board strikes the ground, the back foot jumps up… the tail of the board will follow up with the foot when the front foot slides forward slightly, which pivots the tail of the board upwards. Since the front truck comes off the ground first, getting the back truck up is the trick.

Now, I might not be able to skate to save my life, but I can do a little physics. So here's a thought - maybe I can use physics to learn how to do an ollie. Here's the plan. I'm going to open up the above video of skateboarder Adam Shomsky doing an ollie, filmed in glorious 1000 frames-per-second slow motion, and analyze it in the open source physics video analysis tool Tracker.

Before we show you how to ollie, let’s get familiar with the legends that brought this skateboard trick to the masses.  If it were a person, the history of ollie would start way back in 1974, when Alan Gelfand got his first skateboard from his father after his family moved to Hollywood, Florida from New York state. It didn’t take him too long to get the hang of it; he won the South Florida Skateboard championships two years later.

Skateboarding started in California in the 1950s.[2] The first skateboards were made from roller skates (attached to a board).[3] Skateboarding gained in popularity because of surfing; in fact, skateboarding was initially referred to as "sidewalk surfing". Initially, skateboards were handmade from wooden boxes and planks by individuals. As the sport became more popular, companies started manufacturing skateboards. Boards are also continuing to evolve as companies try to make them lighter and stronger or improve their performance.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
