Question

Какой вид трения имеет место:А) когда вы ходите?

Answer 1

Это называется трением покоя.

Answer 2

Types of Friction

When you walk, the type of friction that occurs is called kinetic friction. Kinetic friction is the force that opposes the motion of two surfaces that are in contact and sliding against each other. It occurs when there is relative motion between the surfaces.

Kinetic friction can be further classified into two types:

1. Sliding Friction: Sliding friction occurs when two surfaces slide against each other. For example, when you walk on the ground, the soles of your shoes slide against the surface, resulting in sliding friction.

2. Rolling Friction: Rolling friction occurs when an object rolls over a surface. It is generally lower than sliding friction because rolling involves less surface contact. When you walk, the rolling friction between the soles of your shoes and the ground also contributes to the overall friction.

It's important to note that the amount of friction experienced while walking can vary depending on various factors such as the type of surface, the condition of the surface, the weight of the person, and the type of shoes worn.
