Fire is a chemical reaction. You are able to see the oxyidation reaction taking place. And fire doesn't always go upwards. Look at a torch. The flames travel in the direction of the combstion air.
In a normal fire, such as in a fireplace the combustion air is traveling upwards due to convection. That is the air current created by the heat that the fire produces.
But in other circumstances the combustion air if directed correctly can go in any direction at all.

Heavier than air objects with a mass fall. Fire is an element, it is the result of chemical and physical reactions.The Fire is a gas. Some gases are lighter than air and parts of the fires combustion rise, for a time.

The law of gravity applies to matter with mass. Depending on the weight of the mass, we can assess its gravitational fall. In the case of fire there is no mass present unless the burning object becomes ash or embers in which case it eventually falls to the earth.

Because it has a lower density than the medium surrounding it (Air) thus it rises. This, coupled with the kinetic energy it possesses, causes it to always be in an upward motion

Matter falls back down to earth due to its mass and the force of gravity acting upon it. Fire is not matter... and because everything warm rises, so does fire.

gravity only brings down n a matter form like a rock is solid but fire will rise cause of it not being a solid it's simaller to a gas wich will flot on the wind curents and cause of the heat heat rises that is what causes it to continu to go up thats the simple way of putting it im not gana get technical unless u need for me to be lol

Because fire is warm and warm air has less density, so it rises up
