The results show all of the expected features of the meniscus under the gravitational force. A brief discussion is also made on the effect of the errors on the results. The method is further validated by its agreement with the numerical solutions reported in the existing literature.doi:10.1016/B978-0-12-819626-7.00003...
As γS, γL and θ are relatively easily measured, Young's equation plus contact angle measurements would present an easy method for finding the interfacial tension, γSL, between S and L. To a certain extent that is indeed the case but it should not be overlooked that in polar systems ...
Gravitational force is a non-contact force and is an attractive force between two objects with mass. For example, Earth exerts a gravitational force on the Moon. Normal force is a force that acts perpendicular to the surface. Specifically, it is a contact force that pushes back on an object...
Astute students of physics 1 will recognize the sum of kinetic energy plus gravitational potential. In other words: this is a derivation of the conservation of energy for free-falling objects. A more general treatment can be done usingNoether’s Theorem, which says that every symmetry produces a...
The drag equation calculator helps you compute a force exerted on a moving object immersed in a fluid. Reading the text below, you will discover what the equation for drag force is, how the shape of the object influences the force and what the drag coefficient is. What is the equation for...
There is a downward gravitational force equal to mg , where g is the acceleration due to gravity. There is also a frictional force resisting the motion, which we assume to be proportional to the speed of the bob with a coefficient of friction k . Using Newton's second law of motion, ...
What is Coulomb's law? Learn the formula and calculations involved in finding the electrostatic force between charged particles, with some examples.
* * Gravity Equation Gravity models begin with Newton’s law for the gravitational force between two objects i and j: The gravitational force is directly proportional to the masses of the objects (Mi and Mj) and indirectly proportional to the distance between them (Dij). Gravity models utilize...
Particle in a conservative force field The motion of a single particle in aconservative forcefield (for example, the gravitational force) can be determined by requiring theactionto be stationary, byHamilton's principle. The action for this system is wherex(t) is the position of the particle ...
Sketch the pair UR and UT for θ = 0, +π/6, −π/4, +π/2, −4π/3, π. Draw UT with its tail at the tip of UR. The next step in finding the equations of motion of the pendulum is to use some basic vector geometry. The gravity vector is simple in x-y coordinates,...
