就是和一个平面垂直的力。Normal force翻译过来是正向力，你也可以叫它支持力。但是支持力可能不是单方向，其中和平面垂直的component才是normal force."In mechanics, the normal force Fn is the component, perpendicular to the surface of contact, of the contact force exerted on an object by,...
The normal force is always perpendicular to the surface where the weight is applying some force. In fact, the word normal means perpendicular.How to find the normal force To find the normal force, just put all the forces on the y-axis. Notice that we show nothing on the x-axis. The ...
Normal Force: In physics and engineering, the normal force refers to a force that applies perpendicular to a surface on which an object rests. The normal force can be applied by the ground, a floor, or a slope such as a slanted object. ...
Normal force, abbrevation is \( F_n \), in physics describes the force exerted by a surface on an object in contact with it, perpendicular to the surface. It is called the "normal" force because it acts perpendicular or normal to the surface at the point of contact. The normal force...
Normal Force: The normal force is a reaction force that a surface exerts upon an object resting on the surface. The surface pushes against the object in a direction normal (perpendicular) to the surface itself. It is always only as large as it needs to be to prevent acceleration through th...

Normal force is the perpendicular force that the surface exerts on an object. For example, if you put a book on a table, there is a gravitational force that is pulling it toward the ground. To counteract this force, the table exerts a force on the book, preventing it from falling. This...
The word "normal" in this context is a mathematical term that means "perpendicular to a surface." In general, two objects in contact with one another push on each other in the direction perpendicular to the contact surface. Now, at the top of the loop, the rollercoaster car must have a...
The thermocapillary motion of a fluid droplet in a constant applied temperature gradient perpendicular to a plane surface is analyzed. The exact solution for the temperature and velocity fields in the quasisteady situation is obtained by using spherical bipolar coordinates, and the asymptotic formulas ...
When a force is acting tangentially on a surface, the corresponding stress is referred to as shear stress. When a force is perpendicular (normal) to a surface, it is termed normal stress. Pressure is a normal stress. When a fluid flows through a conduit, it is acted upon by the normal...
