1. Unknown_Error
2. Elasticity is also called & quot; Elastic force;. When an object is deformed by an external force, if the external force is removed, the object can return to its original shape; Elasticity & quot;. Its direction is opposite to that of the external force that deforms the object
there are many kinds of deformations of objects, so the elastic force proced also has various forms
1. Pressure and supporting force are proced between the objects with shrinkage deformation
direction: it is perpendicular to the contact surface and points to the pressed or supported object
2. Hang an object on the spring, and the object elongates the spring. The elongated spring needs to return to its original state and proce upward elastic force, which is its pulling force on the object.

3. Elastic force is proced by elastic deformation of objects in contact with each other. If there is no contact between objects, or if there is contact but no elastic deformation, there will be no elastic force
while gravity is proced by the attraction of the earth, which is a component of the universal gravitation of the earth to objects
so elastic force and gravity are two forces with different properties, One is proced by elastic deformation, the other is the universal gravitation between objects
while gravity is proced by the attraction of the earth, which is a component of the universal gravitation of the earth to objects
so elastic force and gravity are two forces with different properties, One is proced by elastic deformation, the other is the universal gravitation between objects
4. In force analysis, it is & quot; Gravity, elasticity, friction;, The forces acting on an object are all these three forces. It's elastic force
5. (1) Pressure, supporting force and pulling force are named according to the effect of force
the pressure, supporting force and pulling force are all caused by the deformation of the object
(2) elastic force is named according to the nature of force,
after an object is deformed by an external force, if the external force is removed, the object can return to its original shape, which is called "elastic force". Its direction is opposite to that of the external force that deforms the object. Because there are many kinds of deformations of objects, the elastic force proced also has various forms. For example, when a heavy object is placed on a plastic plate, the bent plastic will return to its original state and proce upward elastic force, which is its supporting force to the heavy object. When an object is hung on a spring, the object elongates the spring. The elongated spring needs to return to its original state and proce upward elastic force, which is its pulling force on the object. Not only plastics and springs can be deformed, but any object can be deformed. There is no object without deformation. However, some deformations are obvious and can be seen directly; Some of the deformations are quite small and can only be detected by instruments.

6. A. Generally speaking, the pressure, supporting force and the pulling force of the rope are elastic, so a is correct
B. the direction of the elastic force generated on the light rope is always on the straight line where the rope is located and is the same as the direction of the rope's recovery deformation, so B is correct
C. if objects contact with each other and become visible, they will proce elastic force, so C is incorrect
D, the direction of pressure and supporting force are always perpendicular to the contact surface, so D is correct
this question is incorrect, so choose: C

7. The elastic force is proced by the deformation of the object. The pressure is not proced by the deformation of the object, but by the gravity, the supporting force and the pulling force!

(2) elastic force is named according to the nature of force,
after an object is deformed by an external force, if the external force is removed, the object can return to its original shape, which is called "elastic force". Its direction is opposite to that of the external force that deforms the object
there are many kinds of deformations of objects, so there are different forms of elastic force. For example, when a heavy object is placed on a plastic plate, the bent plastic will return to its original state and proce upward elastic force, which is its supporting force to the heavy object. When an object is hung on a spring, the object elongates the spring. The elongated spring needs to return to its original state and proce upward elastic force, which is its pulling force on the object.

9. Pressure, supporting force and pulling force are all elastic according to the nature of force; Elastic force;. When an object is deformed by an external force, if the external force is removed, the object can return to its original shape; Elasticity & quot;. Its direction is opposite to that of the external force that deforms the object. Because there are many kinds of deformations of objects, the elastic force proced also has various forms
the pressure and supporting force are the elastic force between the objects that contact each other and contract, and the pulling force refers to the elastic force between the objects that stretch
pressure, supporting force and pulling force are all named according to the effect of force.
