Circular force examples

Assume that each star undergoes uniform circular motion such that the stars are always a fixed distance . s. apart (rotating counterclockwise in Figure 9.5). Example of centripetal force is electrons revolving around the nucleus in a circular orbit in an atom. The centripetal force is occurring due to electrostatic attraction between electrons (negative charge) and nucleus (positive charge).

Movement of the planets around the Sun, movement of moon encircling the earth, The electron orbits the nucleus in an atom, a car or a bike taking a circular bend, Washing machine, etc. Applying the concepts of this force many devices like washing machines have been designed. Centripetal force is the force that keeps a body in a circle. It is also called center seeking force. While A force that keeps a body away from the center of the circle is called centrifugal force. Banking of the roads, washing machine dryer, the cream separator are some examples of centripetal and centrifugal force. Circular motion is everywhere around us, from the spinning of the wheels on your bicycle to the fans in your living room.

First picture shows the motion of a stone tied up with a string doing circular motion.

Assume that each star undergoes uniform circular motion such that the stars are always a fixed distance . s.

What is the direction of the centripetal force.

Circular motion need not be uniform, and speed of motion may vary in a non-uniform circular motion. Car tyres, wheel, athletes running on circular race tracks, orbital satellites are examples of circular motion. While satellites move at uniform speed, athletes, car tyres may keep changing their speed. 16.6K views Central force is mainly experienced by the objects that are in a uniform circular motion as the force holds the object at a fixed point. Gravitational force and spring force are examples of central force In your premise, you already accept the truth of the claim you are attempting to make. It sounds complicated, but it is easily understood with some real-world examples. Circular reasoning may sound convincing, but consider who will most likely be convinced by a circular argument.

Examples of central forces 1. uniform circular motion 2. force due to gravitation 3. simple harmonic motion 4.

The circular motion may be uniform as well as non –uniform.

T represents the tension of the string towards to the center.
