Question

Our palms feel warm on rubbing because of frictional force.

• A. True
• B. False

Answer 1

The correct option is A True

1. When you rub your hands together then the action of scraping the surface of your skin back and forth against each other causes the molecules in your skin to move a little faster.
2. The faster that molecules move, the higher the temperature.
3. So the friction of rubbing your hands together makes them feel warmer.

So the above statement is true.
