Whenever you stand somewhere, both gravity and the normal force are at work. You can see this if you stand on a scale. The number that appears is your weight - the force pulling you down to the earth due to gravity. But you could also see this number as the normal force since it'...

What is the x component Fx of the resultant force? Give an example of a force counteracting a pulling force. Which force acts opposite the direction of displacement of an object? What are external forces and internal forces acting on rigid bodies?
Resistance is a type of force that opposes the change in the direction of the object. The direction of the resistance force is opposite to the direction of the applied force. Some type of resistance forces is as follows. Frictional force Inertia force Air resistance force Visc...
That is, the two disciplines break the chain of the original internal structure, disrupt the theoretical level, discrete knowledge particles, so that they become active, on this basis to refine a new basic theoretical level. With the extension of logic, under the resultant force of multi ...
