What Are The Physics of Fireworks?

  • by

Exploding fireworks happen when series of chemical reactions occur one after the next. The addition of heat to the fireworks will trigger the firework which kick-starts a chemical reaction. After the chemical compounds that are packed inside the firework burn with oxygen they change into other gases such as carbon monoxide, nitrogen and carbon dioxide, in the form of smoke which is a result of the fumes from fireworks.

What causes Fireworks to explode in different colours?

The colours are created by the use of metal salts in fireworks. The most commonly used metal salts in fireworks include: strontium carbonate (red fireworks) as well as calcium chloride (orange fireworks), sodium Nitrate (yellow fireworks) as well as barium chloride (green fireworks) and copper chloride (the blue fireworks). The most common type of fireworks is purple. They are made with a mixture of strontium (red) and copper (blue)

If a firework is ignited and ignited, it is then pushed to the air by a lift charge. This is all black and explosive inside a narrow space which is ignited and causes an immediate heat and gas increase that can create a fireworks that can reach up to 1,500 feet (300 metres) into the sky.

What are The Physics of Fireworks?

The solid substances that are compressed into the cardboard packaging don’t necessarily rearrange themselves to form other compounds. Most of the chemical energy stored in them transforms into four other forms energy (light energy, heat, kinetic energy, and sound).

Based on the fundamental rule of physics called energy conservation (one of the most important and fundamental scientific rules governing the functioning of the universe), the cumulative chemical energy that is packed into the fireworks before it ignites should be the same as the cumulative remaining in it after it explodes, and the energy released as sound, heat and light.

Additionally, Physics also demonstrates why firework explosions are released into the air. The energy is no more than that of the missile. When it explodes, in similar fashion to space rockets or jet engine the firework is driven by reaction-and-action (this is also known as Newton’s third law of motion). As soon as the powder ignites within the charge, it gives off the hot exhaust gases, which then fire backwards. The energy generated by the exhaust gases fired backward is like the blast that is released out from a rocket engine. It generates an oppositional “reactive” force that shoots the firework up, flying in the air.

If you take a look at the different pictures of the firework on this page, you will see another aspect of fascinating physics happening also. Notice how fireworks create color-coordinated blasts? If there’s one part of the fireworks going left, another one goes to the right. There’s no way to tell if a firework is sending all the stars to the left or a greater number of blasts on the left instead of to the right. the blast is still perfect.
Why does this happen? It’s because of a different fundamental law of physics known as momentum conservation.

The power of a firework must be identical prior to when it ignites and afterwards. After an explosion. Moreover, the explosions need to be offset precisely by the proper explosion.

A Few of the Best Fireworks For Beginning Fireworkers

If you’re new at the entire launch your own firework thing then it would be a good idea to do your first experiments with smaller fireworks such as catherine wheels and repeaters. Here are a few of our best fireworks for beginners:

Angel Dust Fireworks

Angel dust fireworks, once illuminated, shoot out thousands of jaw dropping stars. They’re also silent, which is great if you have noisy neighbors.

If you’re looking for stunning fireworks but do not want to put up and launching rockets, it’s a good idea to look into barrage packs. THey can be lit and left to ascend one after the other giving you a spectacular display of light.

The Strike A Rose Firework

This surprisingly quiet spectacle of firework produces the most amazing display of light with little effort for the person who is using it. Simply set it up, flick the fuse , and then enjoy the spectacle! It’s a fireworks show with the effect of a crossette. It’s like a star , which splits into four stars with a cross shape.
