What is an Ollie
Definition: A skateboarding trick where the skateboarder pops the skateboard into the air. The effect is the skateboarder jumping with the skateboard stuck to his or her feet. (

An Ollie On a Skateboard
Analyzing the Ollie
Biomechanics Project
Stand on the board.
First Step
Adjust your feet with your front foot near the middle of the board and your back foot on the tail of the board.

The ball of your back foot should be half hanging off the edge of the deck's tail, or back. The ball of your front foot should be central to the deck, somewhere between the bolts.

Second Step:
Bend your knees and crouch down.
Start off in a stationary position. Balancing your crouch properly is crucial. Don't bend your back too much and don't stick your bottom out too far. Try to drop down and keep your shoulders level with your feet.
Try to stay on the balls of your feet, especially when crouching.

Third Step:
Jump up, and kick down the back of your board at the same time
.
A good strong pop is very important; it's the power behind your ollie. It's called a pop because of the noise of your deck hitting the ground, which will make it bounce.

Timing of the pop is crucial. After jumping, pop the board as soon as you feel your weight lessening on the board.
This may seem tricky, as the jump and pop seem instantaneous, but visualizing it this way helps a lot.

Fourth Step
Slide your front foot as soon as you start jumping.
Turn your front foot inward and slide up the front of the board in a rolling motion. Bring your back leg up toward your chest as you do this.
Remember that this step must be performed at the same time as jumping. Sliding too soon will result in an ollie with little height; sliding too late will result in an ollie that doesn't get leveled out at its highest point.

Fifth Step
Pull your knees up towards your chest.
Exactly how far you need to do this depends on how high your ollie is, but the board can only go as high as your feet, so if you want your ollie to be high you have to bring those feet up higher.
Sixth Step:
Level out with both when your front foot has slid all the way up, keeping pressure on the board as it begins to fall down.
Make the board level to the ground while in mid-air. In other words, don't have the front of the board sticking up in mid-air. This technique will help tremendously when you get to jumping gaps.
Seventh Step:
Try to land both feet at the same time, preferably with your feet as close to their respective trucks as possible.

If you land an ollie with both feet in the middle of your deck, it's going to snap. Likewise, if you land on your nose and tail, they could break off. Make sure you bend your knees to absorb the shock when you land.
Last Step
Not only is skateboarding fun, but it challenges your body physically to manipulate a skateboard to do tricks and "defy gravity".
-Skateboarding can also be considered a way of expression or just a method of transportation.
- Skateboarding can also be a source of income to some skateboarders
Skateboarding
Skateboarding is an action sport which involves riding and performing tricks using a skateboard.

The Ollie:
Results:
The Skateboard during the Ollie works as a lever.
A lever can be defined as an object that is used with a pivot point to multiply the force that can be applied to another object.
Using the back wheels as the pivot point you push down the back tail moving the front of the skateboard into the air quickly.
The skateboard keeps going up into the air and then you open the lever by hitting (or popping) the tail on the ground and use your feet to change the angle of direction.
It causes the skateboard to leave the ground.
This lever motion happens quickly and it appears that the board is like a seesaw for most of the motion.
The End
1. The skateboard has a constant force at the middle of the board known as the center of gravity, which also serves as the pivotal point of rotation for the trick.
2. As we stand on top of the board we are applying a downward force due to our weigh.
3. While standing on top of the board there is an upward force at the wheels, which is the force of the ground.
4. During the pop of the Ollie, we apply a force only to the back tail of the skateboard from the downward pushing motion.
a. The force of the ground continues to push up against the board as the back tail hits the ground and the center of gravity of the board does not change
5. The sliding motion cause a force in that direction and a force perpendicular to that directional force
6. After this point, the board has reached its maximum height and will fall along with the skater due to the downward force of gravity.
a. Then during landing the skater bends their knee to absorb some of the impact of shock asserted from the ground.
