# What forces are involved in diving?

Gravity pulls the diver towards the water and as the diver falls they accelerate, or fall faster, as the effects of gravity take greater affect. The diver has to perform their dive, with twists, turns and somersaults before they have been pulled into the water by the force of gravity.

## What are the laws of physics that are with reference to diving?

As a diver, Boyles law affects you every time you enter the water. Air spaces in the body are subjected to pressure and volume change, in direct proportion to your depth. Without doubt, understanding Boyle’s Law is very important in scuba diving. Note that Boyle’s law also relates to gas density.

## What is the physics of a diving board?

Newton’s 3rd Law of Motion states that for every action, there is an equal and opposite reaction. That’s what makes it possible for divers to project themselves from the diving board or platform. The diver puts energy into the diving board or platform, which is then transferred back to the diver.

## How do the divers take advantage of Newton’s law of motion?

The third law of motion states that every action has an equal and opposite reaction. You can see equal and opposite forces interact when you jump down on a diving board and release, the diver moves in the opposite direction(up in the air).

## Why do divers spread their knees?

A platform diver must generate upward and forward momentum off the platform by bending the knees (almost like loading a spring) and pushing off the hard platform surface with toes, ankles, knees and hips, while also using arm swings and/or a running approach to generate more height and flip.

## How is Boyle’s law related to diving?

Boyle’s Law is also important to divers because it means that if a diver takes a lung- ful of air while he is underwater, that air will expand in his lungs as he rises to the surface. If he holds his breath, or ascends too rapidly (like a cork) the expanding air can rupture his lungs.

## How does Dalton’s law apply to diving?

Dalton’s Law of Partial Pressures allows a diver to predict how much of a specific gas will dissolve in her blood at a given depth. This is important, because some gases become toxic or cause mental impairment when their partial pressure in the blood rises above a particular level.

## How does Charles law apply to diving?

Divers rely on equipment to adapt and become part of the underwater world, and having a basic knowledge of science helps ensure safety while diving. A common example of this is with Charles’ Law. Charles’ Law states that at a constant volume, the pressure of gas varies directly with absolute temperature.

## Why do divers curl their toes?

It actually means pointed feet, not toes. Curling your toes while keeping your foot flat looks quite unattractive during dives. When your coach says, “Point your toes,” he/she wants you to extend your foot from the ankle.

## Why do divers hold their hands flat?

Since every single diver did it, we assumed there was some — maybe it un-tenses their muscles, or something technical like that. But as it turns out, it’s just a way to relax and keep warm, according to Canadian diving coach Mitch Geller.

## Why do divers tape their toes?

This tape, known as ‘k tape’ or kinesiology therapeutic tape, is a special kind of tape used to relieve pain in joints, ligaments and muscles – with divers donning it on areas which can hit the water during dives at high velocity to lessen the chance of swelling and help maintain mobility.

## What law of motion is diving?

The diving board pushes back against the personÕs feet equally. The reaction force pushes the person forward and the diving board backward, in opposite directions. The Third Law of Motion says that for every action there is an equal and opposite reaction.

## Why does a diver use the tuck position inertia?

By pulling the legs and arms closer to the point of rotation, the moment of inertia decreases and the angular velocity increases. A tighter tuck means a faster rotation.

## Why is speed important in diving?

Slow Versus Best Ascent Speed Of course, it is important to have a max ascent speed – we decompress as we ascend, so our speed is a critical method of ensuring that the necessary off-gassing occurs (even on recreational dives) to prevent symptomatic inert-gas bubbles from causing us harm.

## What is the most common injury in diving?

EAR AND SINUS The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.

## Why do divers ice their triceps?

Athletes often use ice packs to help sore muscles recover, as the cold reduces inflammation and lowers the risk of muscle soreness and injury. Tricep injuries are common among divers, as the muscle group can be affected by the impact of the water as the diver enters a pool.

## Is diving painful?

As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.

## Why is it important to know the diving physics as a diver?

An understanding of the physics is useful when considering the physiological effects of diving, breathing gas planning and management, diver buoyancy control and trim, and the hazards and risks of diving.

## Is Cartesian diver Boyle’s Law or Charles Law?

The scientific principle applied to the Cartesian Diver experiment is Boyle’s Law. The diver is a small object whose density varies with pressure.

## Why does diving 30m below sea level?

Compared to air, however, water is relatively heavy, with a column of 10 meters of water having roughly the same mass as a column of air the height of our atmosphere. This means that descending 30 meters deep into water has a much greater effect on pressure because of water’s relatively high mass.

## What would happen to a diver who does not exhale while surfacing from a 30m dive?

If divers must make emergency ascents from this depth they must remember to breathe out regularly as they return to the surface. If they don’t, the pressure of the air in their lungs will cause their lungs to expand.

## Why do scuba divers experience bends?

The Bends is an illness that arises from the rapid release of nitrogen gas from the bloodstream and is caused by bubbles forming in the blood and other tissues when a diver ascends to the surface of the ocean too rapidly. It is also referred to as Caisson sickness, decompression sickness (DCS), and Divers’ Disease.

## Why is it important to a scuba diver to know about gas laws?

This scuba diving gas law is very important for us as divers as it allows us to determine when a certain component’s partial pressure will reach a threshold. From your Open Water Diver course, you remember the increasing toxicity of breathing gases, namely oxygen and nitrogen.

## Why does air compress underwater?

Simply put-as a diver goes deeper into the water, the pressure on everything becomes greater. The volume of air in the dive tanks is getting smaller while the pressure rises. Remember from the basics that you can compress air. This also means that the air in the divers lungs also becomes compressed when at depth.
