Examples of strong force in the following topics:
-
- Nuclear force is the force that is responsible for binding of protons and neutrons into atomic nuclei.
- The nuclear force is the force between two or more component parts of an atomic nuclei.
- The nuclear force is now understood as a residual effect of an even more powerful "strong force" or strong interaction.
- These nuclear forces are very weak compared to direct gluon forces ("color forces" or "strong forces") inside nucleons, and the nuclear forces extend over only a few nuclear diameters, falling exponentially with distance.
- Nevertheless, they are strong enough to bind neutrons and protons over short distances, as well as overcome the electrical repulsion between protons in the nucleus.
-
- The strong nuclear force is the force between two or more nucleons.
- These two forces produce opposite effects in the nucleus.
- The strong nuclear force acts to hold all the protons and neutrons close together, while the electromagnetic force acts to push protons further apart.
- In atoms with small nuclei, the strong nuclear force overpowers the electromagnetic force.
- As the nucleus gets bigger, the electromagnetic force becomes greater than the strong nuclear force.
-
- The origin of the energy released in fusion of light elements is due to an interplay of two opposing forces: the nuclear force that draws together protons and neutrons, and the Coulomb force that causes protons to repel each other.
- This force, called the strong nuclear force, overcomes electric repulsion in a very close range.
- The effect of nuclear force is not observed outside the nucleus, hence the force has a strong dependence on distance; it a short-range force.
- At nucleus radii distances, the attractive nuclear force is stronger than the repulsive electrostatic force.
- Describe the electrostatic and strong nuclear forces and how they act to oppose or promote a fusion reaction
-
- Forces act in a particular direction and have sizes dependent upon how strong the push or pull is.
- Forces act in a particular direction and have sizes dependent upon how strong the push or pull is.
- In this simple one-dimensional example, without knowing the direction of the forces it is impossible to decide whether the net force is the result of adding the two force magnitudes or subtracting one from the other.
- Associating forces with vectors avoids such problems.
- Forces are resolved and added together to determine their magnitudes and the net force.
-
- The vast majority of them were drafted into the civilian work force to replace conscripted men or work in greatly expanded munitions factories.
- This proved that women were capable of taking on work in the employment front, and therefore forced the voting controversy that was later to come.
- Samuel Gompers, head of the American Federation of Labor (AFL), and nearly all labor unions were strong supporters of the war effort.
- The strikes ultimately failed, forcing unions back to positions similar to those around 1910.
- Examine the new labor force of women, and the strong support of labor unions, during World War I.
-
- The molecules in any sample of matter experience intermolecular forces, which are attractive or repulsive forces between atoms or molecules within the sample.
- These cohesive forces are especially strong at the surface of a liquid, resulting in the phenomenon of surface tension.
- It occurs when the intermolecular attractive forces between the liquid and the solid surrounding surfaces (adhesive forces) are stronger than the cohesive forces within the liquid.
- Adhesion forces between the fluid and the solid inner wall pull the liquid column up until there is a sufficient mass of liquid for gravitational forces to counteract these forces.
- The curvature of the surface at the top of a column of fluid in a narrow tube is caused by the relative strength of the forces responsible for the surface tension of the fluid (cohesive forces) and the adhesive forces to the walls of the container.
-
- In mammals there is a strong overlap between the optimum and actual resting length of sarcomeres.
- The force-velocity relationship in muscle relates the speed
at which a muscle changes length to the force of this contraction and the
resultant power output (force x velocity = power).
- The force generated by a muscle
depends on the number of actin and myosin cross-bridges formed, a larger number
of cross-bridges results in a larger amount of force.
- As velocity increases force and therefore power produced is reduced.
- Although force increases due to stretching with no velocity zero power is produced.
-
- There are many cases where a particle may experience no net force.
- Or there could be two or more forces on the particle that are balanced such that the net force is zero.
- Recall that the magnetic force is:
- In this case a charged particle can continue with straight-line motion even in a strong magnetic field.
- In the case above the magnetic force is zero because the velocity is parallel to the magnetic field lines.
-
- The drag force is the resistive force felt by objects moving through fluids and is proportional to the square of the object's speed.
- Another interesting force in everyday life is the force of drag on an object when it is moving in a fluid (either a gas or a liquid).
- You feel the drag force when you move your hand through water.
- You might also feel it if you move your hand during a strong wind.
- This video walks through a single scenario of an object experiencing a drag force where the drag force is proportional to the object's velocity.
-
- Inside forces include strategic and human resource changes, while outside forces include macroeconomic and technological change.
- Economics - The 2008 economic collapse is a strong example of why adaptability is important.
- There are many inside forces to keep in mind as well, ranging from employee changes to cultural reform to operational challenges.Understanding where this change is coming from is the first step to timely and appropriate change management.
