When we rub our hands, we use our body's energy to generate kinetic energy. This causes friction between our hands, which causes heat to be produced. Hence we feel warm.
thermal energychemical energy is transferred to thermal, sound, and motion energy. Thermal
When you vigorously rub your hands together, mechanical energy is converted into thermal energy through the friction generated between your hands. The kinetic energy of the movement is transformed into heat energy, causing your hands to warm up.
The friction created by rubbing the sticks together created an energy hot enough to make a flame. Sorry, I do not know enough about it as yet, but I am taking a class in science and it is fascinating. Come back to me maybe next week, I may be better able to answer. Thanks
Walking: we could never walk without friction. We would have been slipping in one place. Rubbing hands together: We rub our hands together to keep them warm in winter. The warmth is generated by friction. Brakes: Brakes help to stop a vehicle in motion. Braking increases friction.
In an alarm clock, electrical energy from the battery or power outlet is transformed into mechanical energy to move the clock hands or generate sound energy for the alarm.

If you use non-antibacterial soap and rub your hands together with it and water for like 15 seconds, that releases the germs, but does not kill them. So then you put your hands under water and that washes the germs away.

A very simplistic explanation:The movement of your hands together create a concussive force that is transformed into vibration. That vibration is conveyed to your ears via the atmosphere, where your ears transform it into electrical energy that your brain translates into sound.
Place the finger tips of both hands together, then burst apart to wide open hands.
The way to make praying hands symbol is to place the palm of the hands together with the fingers touching. The thumbs should line up along with the fingers for a praying motion.

That isn't such a good idea. Fingers that cold can't feel how hot the water is, and you might end up scalding them instead. Never plunge a numb body part into water unless you know the temperature is safe. You need to test with a body part with normal sensitivity first. The rubbing is also a so-so thing. If you already have developed frostbite, you have ice crystals in your tissues. Rubbing will damage even more tissue, causing a bigger-than-necessary injury and slow down healing. Rubbing is ok though as long as you're sure there's no possibility of freezing.
Place the hands facing each other; then move them together sideways in 2 or 3 short movements.
The buildup of electric charges in one place can lead to static electricity. This accumulation of charges occurs when electrons are transferred from one surface to another, creating an imbalance that can result in sparking or electric discharge. It is commonly experienced when rubbing two objects together, such as when shuffling feet on a carpet.
