Sentences with phrase «normal force»

The normal adult shape of a ball and socket are a result of all factors, including normal forces of the ball in the socket, being within «normal» limits during development.
Three that anything outside of the historically normal forcings can be attributed to human produced CO2.
The 2 - minute rest period may have allowed for a reduction in deep mechanoreceptor activation, leading to a restoration of the H - reflex, allowing for normal force production.
Researchers of the UvA Institute of Physics, the UvA Van't Hoff Institute for Molecular Sciences, the MicroTribology Center µTC in Freiburg and the Karlsruhe Institute of Technology have now studied this proportionality between friction and normal force more closely, using molecules that luminesce under pressure.
When a larger normal force (pressure) is applied, the «hilltops» on the spherical surface are flattened more, resulting in a larger contact area between the sphere and the glass plate.
This presentation includes: A definition of normal force Pressure equation with worked example Pressure equation problems with solutions Rearrangin...
Hence, it is not the electromagnetic repulsion between electrons and nuclei that is responsible for two wood blocks that are left on top of each other not coalescing into a single piece, but rather it is the exclusion principle applied to electrons and protons that generates the classical macroscopic normal force.
«We checked it (Sanchez's hamstring) When you have normal force and normal stretch there is no problem and he had that.
Once at the right level, a latch tightener multiplies your normal force so that the base is secured as tightly as possible with less effort on your part than is needed with other models and brands.
At this point, the sideways driver is at the mercy of four forces: static friction between the tires and the surface; the normal force (basically the force with which the surface pushes back at an object, insisting on annoying the surface with its presence); gravity; and the «downward force» (also sideways in this case) of the car, which should have aerodynamic qualities that make it stick more to the wall the faster it goes.
There are two dominant forces that act on the ball during those five milliseconds: the normal force (in the vertical direction) and the friction force, which is parallel to the surface.
As a result, the cell «contracts, but it produces less than normal force,» Sweeney says.
The normal force of the surface on the ball is always upward, slowing the ball's downward velocity and propelling it skyward.
Several theories predict the relation between contact area and normal force, but so far these theories could not be tested with high precision.
The usual interpretation of Da Vinci's proportionality between friction and normal force is that both forces are proportional to this contact area: applying twice the pressure results in twice the contact area, and therefore in twice the friction.
The researchers now show that the existing theories fall short: friction is proportional to the area of contact, as expected, but the contact area turns out not to be proportional to the normal force.
Da Vinci's main result is still used today by many engineers: friction is proportional to the normal force.
The research results show that a better understanding of friction requires changes in the existing models, so that the measured relation between contact area and normal force can be reproduced.
His most important result, the proportionality of friction to normal force, is still used extensively today.
Weight of car - physics tells me that friction is proportional to the normal force, so I figure this doesn't matter
When you mention the normal force, you're talking about the force of the tire patch on the road.
The reality is that the normal force used for kinetic friction to stop the car isn't the tires.
For one, the coefficient of friction decreases as the normal force increases (see this Wikipedia article for more details).
Basic physics tells us that friction is equal to the normal force times the coefficient of friction, i.e:
As the disk is compressed by the normal forces between the vertebrae, the annulus fibrosus bulges upwards and puts pressure on the spinal cord more slowly.
Since gravity is pulling you down, the ground pushes back (called the normal force, NF).
Much like the Normal Force is meaningless without the gravity.
