Where does friction acts when we move?

Best Answers

First I want to point out that when you are walking, when foot is on the ground, it does not move. That means that the sum of the horizontal forces on it are zero. The muscle in your leg is pushing the foot backwards. We know this because if there was no friction, your foot would move backwards. read more

When we walk, we push the ground backwards and since friction opposes relative motion, it acts forward. Imagine the case of threadmill, the belt moves backwards. Which means friction acts in the direction of our motion. read more

Scientists measure friction based on the materials that are rubbing against one another. Velcro against cloth has a high coefficient of friction, which is a measurement of the ease with which two objects move when in contact with one another. The higher the coefficient of friction, the more friction exists between the two objects. read more
