Unlike a soccer ball in mid-flight, a skateboard mid-ollie is being actively steered. This is exactly what makes doing an ollie so hard. It’s not enough to get the skateboard up into the air – you also have to steer it while it’s in the air. In fact, we can work out how you need to steer the skateboard.
What is the science behind an ollie?
When the tail of the board hits the ground, the ground exerts a powerful upward force. This causes the entire board to bounce and begin lifting up into the air. As the board begins to rise, the boarder slides the front foot forward. The friction between the front foot and the board drags the board upward even farther.
What are the physics of skateboard tricks?
What is the physics of skateboarding?
Thrust is what moves the board forward, lift is what moves it upward, drag from the air pushes backward, and weight is gravity’s way of pulling it back down. The speed of the take-off (and the jumping ability of the skater) affects the amplitude, or height, of the jump, which takes the shape of a parabolic arc.
How long does it take to perfect an ollie?
On average it takes between a couple of weeks and 6 months to learn an ollie. It also depends on how long you practice each day. Some practice for 3 hours and others for 1 hour. The fastest way to learn an ollie is by making sure you cover the basics first.
What forces are involved in skateboarding?
When a skater stands still on their board, three forces are acting on the skateboard. First, gravity pulls the board toward Earth. Second, the weight of the skater pushes down on the board. And third, the ground pushes up on the skateboard.
What’s the hardest trick on a skateboard?
The laser flip is probably the hardest flat ground trick to land. It combines a 360 shuv with a varial heelflip. A 360 shuv is when you flick your back foot down and back to make the board spin 360 degrees in the air with no other flips. A varial heelflip is a heelflip combined with a front shuv.
Is it easier to ollie with smaller wheels?
Smaller wheels accelerate faster compared to larger wheels which is great when you only have a short distance between you and an object you want to ollie stairs for example. You need to be able to get as much speed as possible in the least amount of time.
Why can’t I land an ollie?
This can happen for a lot of reasons, but the biggest one is that you are not crouching low enough before your ollie, and not pulling your feet high enough after you jump. When you crouch down, try and touch the ground. When you jump, try to hit yourself in the chest with your knees.
Does skateboarding defy the laws of physics?
While it may seem that modern skateboarders are defying the laws of physics, the truth is that they’re just using them to their advantage. Let’s take a closer look at some fundamental skateboarding moves and the physics principles behind them.
How does the board go up in an ollie?
With the board now completely in the air, the skater slides his front foot forward, using the friction between his foot and the rough surface of the board to drag the board upward even higher. The skater begins to push his front foot down, raising the rear wheels and leveling out the board.
How do you practice ollie when moving?
What force keeps a skateboard moving?
A: The force of gravity is acting on the skateboard. It will pull the skateboard back down to the ground. Once it’s on the ground, friction will slow its motion. Inertia is the tendency of an object to resist a change in its motion.
Is skateboarding faster than running?
Is skateboarding faster than running? Average normal running speed is in the 4 – 6 mph range. Average skateboarding speed is around 9 mph (in the 5 – 12 mph range). Pushing speed on a longboard is 8-9 mph.
Where does the skater have the most gravitational energy?
The skater has the most gravitational potential energy at the bottom of the half-pipe. Gravitational potential energy transforms into kinetic energy when the skater rolls down the side of the half-pipe. The skater transfers gravitational potential energy to the skateboard.
Is it easier to do an ollie while moving?
The momentum of moving forward makes it easier to catch and level out your skateboard after you pop your board. However, doing an ollie while moving is mentally more difficult. Skaters can be afraid of trying to ollie because taking a fall with some speed is much worse than falling while stationary.
Can you practice ollie on grass?
The two biggest parts to doing an ollie are getting the movements right and having confidence that you can do it. Start practicing on a soft surface such as grass or carpet. This will hold your board still as you practice, and won’t hurt as much as concrete if you fall off.
How do I make my ollie more consistently?
Why is an ollie called an ollie?
And how did skateboarding’s ultimate trick get its name? Alan Gelfand had a nickname – Ollie. It was coined by his Hollywood skateboarder friend, Scott Goodman. And when Goodman saw Alan accidentally perform an aerial lipslide, he called it an ollie pop.
Why do skateboarders bend their knees?
One of the biggest reasons for major knee bend is that it increases the size of your push. A bigger push means that you will be able to skate faster, all else being the same.
How does a skateboard withstand tension?
As a skateboarder lifts his arms and body up he feels resistance due to the force of centripetal acceleration which tends to push his body away from the center of rotation o. This resistance is proof that work is being done, and therefore energy is being added to the system.

What should I learn before ollie?
Before you practice an ollie, start learning the hippie jump first. You’ll get a bit of a feeling what it’s like to jump without popping your deck. This is a really easy trick which you can start doing by just jumping on your skateboard and work yourself up.
Do pros use riser pads?
Do pro skateboarders use riser pads? While not all pro skateboarders use riser pads, many do. Riser pads are small pads that fit between the trucks and the skateboard’s deck, and they serve some purposes. This is especially beneficial for street skateboarding, as it can help to reduce the risk of injury.
