Question

при перемещении одного тела по поверхности другого тела возникает сила которая препятствует его жвижению .Как называется эта сила?. ​

Answer 1

Ответ:

Сила трения

Объяснение:

Сила, возникающая при движении одного тела по поверхности другого, называется силой трения. Она приложена к движущемуся телу и направлена против его движения

Answer 2

The Force that Opposes the Motion of an Object on the Surface of Another Object

When one object moves across the surface of another object, a force arises that opposes its motion. This force is called friction. Friction is a contact force that acts parallel to the surface of contact between two objects and opposes the relative motion or tendency of motion between them.

Friction can be classified into two main types: static friction and kinetic friction. Static friction acts on objects that are not yet in motion, while kinetic friction acts on objects that are already in motion.

Static friction prevents the object from moving until a certain force is applied to overcome it. Once the object starts moving, kinetic friction comes into play and opposes the motion of the object.

The magnitude of the frictional force depends on several factors, including the nature of the surfaces in contact, the normal force between the objects, and the roughness of the surfaces.

Friction plays a crucial role in our daily lives. It allows us to walk, drive vehicles, write with a pen, and perform various other tasks. At the same time, friction can also be a hindrance, as it can cause wear and tear on surfaces and reduce the efficiency of machines.

Friction can be reduced by using lubricants, polishing surfaces, or using materials with low friction coefficients. However, completely eliminating friction is not possible.
