## What is the physics behind surfing?

The surfboard rotates until the buoyancy force through the center of mass of the displaced water is aligned with the gravity force on the surfer. As the board rotates, the center of buoyancy—the center of mass of the displaced water—moves toward the back of the board.

## What type of energy is surfing?

As Eric and other surfers know, riding the waves lets you play with energy. By dropping down the face of the wave (pulled by gravity), you gain kinetic energy, the energy of motion. At the same time, you lose gravitational potential energy, the energy of being high.

## How does Newton’s 2nd Law apply to surfing?

Newton’s second law is Force = mass x acceleration so in surfing, if the surfer is accelerating down the wave with a force that is greater than the force of friction against the board, they will accelerate in all different directions. The surfers mass and weight have a great affect in this law.

## Does Weight Affect surfing?

The weight of a surfer doesn’t necessarily affect performance at all. Balance, coordination and fitness are more important than size when it comes to catching waves and performing well in the ocean. Tricks are performed by advanced surfers when riding waves. … Airs are easier for smaller/lighter surfers.

## Why do surfers touch the wave?

Just the action of touching the water will force you to get lower to your surfboard and maintain a low centre of gravity. It will also make you turn harder and faster which will send you back towards the lip of the wave on a more vertical trajectory and give your surfing a more dynamic look.

## Why do surfers drag their hands?

Hand Dragging

Whenever you’re going too fast and heading into the shoulder of the wave, drag your hand – or even both – in the face of the wave to slow down the speed.

## How do waves work surfing?

For river waves or those at artificial surfing facilities, surfers watch waves develop and jump right into the breaking wave. When surfers see a wave they can ride, they paddle quickly to catch the rising wave. Just as the wave breaks, the surfers jump from their bellies to their feet, crouching on their boards.
