to make fire. when you are out in the wilderness and don't have any matches or a lighter. you can rub two sticks together for a while and it will make a fire!
Sticks rubbing together is an example of friction, a force that opposes the motion of two surfaces in contact. When sticks rub together, the friction between them generates heat and can produce sparks, which is why rubbing sticks together is a traditional method for starting fires.
heat energy
Examples of two objects that rub together include rubbing a balloon against fabric to create static electricity or rubbing two sticks together to start a fire.
Rubbing two sticks together creates friction, which generates heat that can ignite the wood. Metals are better conductors of heat, so when two metal pieces rub together, the heat generated is quickly dissipated, making it difficult to generate enough heat to start a fire.
Kinetic energy is movement energy. So when you rub two sticks together, the rubbing is the kinetic energy. The friction that this causes releases heat. Heat is thermal energy. So due to friction you can convert kinetic energy into thermal energy by rubbing sticks together.

Yes, people in prehistory invented this kind of lighting a fire. Rubbing two dry sticks together makes heat and if you are patient enough it will make fire.

Fire by friction!
Using a fire starter such as matches, a lighter, or flint and steel is a more reliable and efficient way to start a fire than rubbing two sticks together. You can also use kindling or fire starter cubes to help ignite the fire more easily.
A box of matches or you could try rubbing two sticks together, but I don't think that would really work.
Cavemen made fire by rubbing two sticks together or using flint to create sparks that ignited dry grass or wood.
