Examples of normal in the following topics:
-
- The normal force, $F_N$, comes about when an object contacts a surface.
- This is the reason that the normal force exists.
- A common situation in which a normal force exists is when a person stands on the ground.
- The second is the normal force.
- Evaluate Newton's Second and Third Laws in determining the normal force on an object
-
- Antiparticles bind with each other to form antimatter in the same way that normal particles bind to form normal matter.
- Antimatter galaxies, if they exist, are expected to have the same chemistry and absorption and emission spectra as normal-matter galaxies, and their astronomical objects would be observationally identical, making them difficult to distinguish from normal-matter galaxies.
-
- Spherical waves come from point source in a spherical pattern; plane waves are infinite parallel planes normal to the phase velocity vector.
- A plane wave is a constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of constant peak-to-peak amplitude normal to the phase velocity vector .
- Plane waves are an infinite number of wavefronts normal to the direction of the propogation.
-
- The components of the normal force $N$ in the horizontal and vertical directions must equal the centripetal force and the weight of the car, respectively.
- The only two external forces acting on the car are its weight $w$ and the normal force of the road $N$.
- (A frictionless surface can only exert a force perpendicular to the surface—that is, a normal force. ) These two forces must add to give a net external force that is horizontal toward the center of curvature and has magnitude $\frac{mv^2}{r}$.
- Only the normal force has a horizontal component, and so this must equal the centripetal force—that is:
- From the figure, we see that the vertical component of the normal force is $N\cos\theta$, and the only other vertical force is the car's weight.
-
- Also, let's ignore the normalization for the moment:
- This completes the proof, but now what about the normalization?
- If we put the symmetric $1/\sqrt{2 \pi}$ normalization in front of both transforms, we end up with a left-over factor of $1/\sqrt{2 \pi}$ because we started out with two Fourier transforms and we ended up with only one and a convolution.
- On the other hand, if we had used an asymmetric normalization, then the result would be different depending on whether we put the $1/(2 \pi)$ on the forward or inverse transform.
- This is a fundamental ambiguity since we can divide up the normalization anyway we want as long as the net effect is $1/(2 \pi)$ .
-
- Line of impact - It is the line which is common normal for surfaces are closest or in contact during impact.
- When dealing with an incident body that is nearly parallel to a surface, it is sometimes more useful to refer to the angle between the body and the surface, rather than that between the body and the surface normal (see ), in other words 90° minus the angle of incidence.
- The angles between the body and the surface normal areindicated as α and β.
-
- There are mainly three kinds of forces: Gravity, normal force (between ice & pucks), and frictional forces during the collision between the pucks
- With this in mind, we can see that gravity and normal forces are external, while the frictional forces between pucks are internal.
- (Gravity and normal force on each puck have the same magnitude, but are in the opposite directions) Therefore, we conclude that the total momentum of the two pucks should be a conserved quantity.
- Also note that, in the previous example, if we include the rest of the Earth in our system, the gravity and normal forces themselves become internal.
-
- Normal plasma behaves like a Newtonian fluid at rates of shear.
- Typical values for the viscosity of normal human plasma at 37°C is 1.2Nsm-2.
- The viscosity of normal plasma varies with temperature in the same way as does that of its solvent, water.
-
- Normally with each beat the right ventricle pumps the same amount of blood into the lungs that the left ventricle pumps out into the body.
- The sinoatrial node (also commonly spelled sinuatrial node) is the impulse-generating (pacemaker) tissue located in the right atrium of the heart: i.e., generator of normal sinus rhythm.
- The sinoatrial node (also commonly spelled sinuatrial node, abbreviated SA node) is the impulse-generating (pacemaker) tissue located in the right atrium of the heart, and thus the generator of normal sinus rhythm.
- Although all of the heart's cells have the ability to generate the electrical impulses (or action potentials) that trigger cardiac contraction, the sinoatrial node normally initiates it, simply because it generates impulses slightly faster than the other areas with pacemaker potential .
- The reason Purkinje cells do not normally control the heart rate is that they generate action potentials at a lower frequency than the AV or SA nodes.
-
- where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.
- Each point on a surface is associated with a direction, called the surface normal; the magnetic flux through a point is then the component of the magnetic field along this normal direction.
