For the example question on centripetal force, why is it Mg - M(S^2/R) rather than Mg + M(S^2/R)? My thought process was that if normal force equals to the forces in the opposite direction and that since the weight of the ball and the centripetal force both point inward, the normal force would equal the weight + centripetal force rather than minus.

The correct answer is Option 1 i.e A washing machine cleaning clothes.. Key Points. A washing machine cleaning clothes is an example of the centrifugal force. Centrifugal force has the tendency to push the object following a curved path, away from the center of curvature.; This characteristic of centrifugal force is used in washing machines.

1 Washing machine In order to wring excess water out of clothes, a washing machine has a spinning drum that makes use of centripetal force. For this problem consider an item of clothing pressing against the wall of the drum as it spins at a particular angular velocity w. a b 1. Which direction does the centripetal acceleration point?

In summary, during the spin cycle of a washing machine, the water is flung out of the clothes by either a centripetal or centrifugal force, depending on the terminology used. However, the water is ultimately drained through the holes in the inner tub, regardless of the force at play.

The people seated in the ride stay in their respective places due to the centripetal force in action. 2. Orbiting Planets. ... During the rinse cycle of the washing machine, the clothes are placed in the dryer drum. The dryer drum consists of a number of holes in it. When the machine is turned on, the drum is set to the rotation.

It is a real force, and it acts toward the center of rotation. The formula for centripetal force is Fc = mv^2 / r, where Fc is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path. ... When a washing machine spins, the centripetal force is provided by the walls of the drum pushing on ...

Centripetal force, for an object in circular motion, is just the force maintaining the circular motion, the force that prevents the object from flying away tangentially. Unless this force is present, no object can execute a pure circular motion, because in absence of a force, a body moves uninterrupted along a straight line (Newton's first law).

A washing machine is, in effect, a spinning top; thus, when the machine rotates, the centrifugal force exerted by one side is balanced by the same on the other side. A centrifugal force becomes a centripetal force when the force exerted by one side of the machine passes through the center of the machine to act on the other side.

This is because the balance between multiple forces acting on the car is disturbed. Eventually, the centripetal force wins over. Drifting is a stunt the sportsmen perform with cars. It uses the phenomenon of centripetal force/. 4. Washing machine dryer: When you put wet clothes in a washing machine dryer and turn it on, it starts to …

Example of centripetal force: Washing machine dryer Image by Steve Buissinne from Pixabay . This is the most common example of centripetal force in our homes. The motor in a washing machine rotates the drum at high speeds which keeps the clothes moving at high speeds within the confined area. This will ensure a better cleaning action on the …

How does centripetal force help in the washing process? Centripetal force helps in the washing process by effectively removing water from the clothes during the spin cycle. As the drum spins at high speeds, the centripetal force pushes the water outwards through the holes in the drum, leaving the clothes drier and reducing the time …

Project the picture of a washing machine and ask students to explain how centripetal force or centrifugal action is used in this machine? A guiding question can be if the clothes come out of the washing machine soaking wet (dripping) or not? Have students work in partner pairs to work out their explanations.
