How to get to know the meaning of CENTRIPETAL FORCE? Here we watch out to bring you the interpretations, terms and ideas that together make up our fascinating language. There is an agreement among translators about the real explanation and definition of the expression CENTRIPETAL FORCE in English, however depending on the region and mainland, you can get some disparities, and it is true that aside from in writing, equally in the meaning of a few models and nuances. What is the Definition of CENTRIPETAL FORCE? The definition of the word CENTRIPETAL FORCE is: Human centrifuges, extremely large centrifuges, have been used to test the tolerance of astronauts to the effects of accelerations larger than that of Earth’s gravity.↓ What is the definition of Centripetal Force? ↓ Centrifuges are often rated in terms of their centripetal acceleration relative to acceleration due to gravity maximum centripetal acceleration of several hundred thousand is possible in a vacuum. Centrifuges are used in a variety of applications in science and medicine, including the separation of single cell suspensions such as bacteria, viruses, and blood cells from a liquid medium and the separation of macromolecules, such as DNA and protein, from a solution. High centripetal acceleration significantly decreases the time it takes for separation to occur, and makes separation possible with small samples.

You may use whichever expression is more convenient, as illustrated in examples below.Ī centrifuge (see Figure 2b) is a rotating device used to separate specimens of different densities.

Recall that the direction of is toward the center. The two equal sides of the velocity vector triangle are the speeds Using the properties of two similar triangles, we obtain Both the triangles ABC and PQR are isosceles triangles (two equal sides). The direction of centripetal acceleration is toward the center of curvature, but what is its magnitude? Note that the triangle formed by the velocity vectors and the one formed by the radii and are similar. (Because Δ θis very small, the arc length Δ s is equal to the chord length Δ r for small time differences.) (See small inset.) Because ac = Δ v/Δ t, the acceleration is also toward the center ac is called centripetal acceleration. The directions of the velocity of an object at two different points are shown, and the change in velocity Δv is seen to point directly toward the center of curvature. We call the acceleration of an object moving in uniform circular motion (resulting from a net external force) the centripetal acceleration( ) centripetal means “toward the center” or “center seeking.” Figure 1. This pointing is shown with the vector diagram in the figure. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation (the center of the circular path). The direction of the instantaneous velocity is shown at two points along the path. In this section we examine the direction and magnitude of that acceleration.įigure 1 shows an object moving in a circular path at constant speed. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. (If you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion.) What you notice is a sideways acceleration because you and the car are changing direction. You experience this acceleration yourself when you turn a corner in your car.

In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the magnitude of the velocity might be constant. We know from kinematics that acceleration is a change in velocity, either in its magnitude or in its direction, or both. Establish the expression for centripetal acceleration.
