A washing machine's spin cycle rotates wet clothes at high speeds inside a drum with small holes. This process effectively removes water from the fabric. Which of the following statements best explains the mechanical principles involved in this process?
- The drum exerts an inward centripetal force on the clothes, while the water escapes through the holes by continuing in a straight line due to inertia.Cevap
- BThe high-speed rotation generates an outward centripetal force that actively pulls the water toward the edge of the drum.
- CThe circular motion creates an outward reaction force to balance the drum's spin, pushing the water away from the center.
- DThe water has more mass than the fabric fibers, which causes it to experience a greater outward acceleration during the spin.
Cevap
The drum exerts an inward centripetal force on the clothes, while the water escapes through the holes by continuing in a straight line due to inertia.
For an object to move in a circle, there must be an inward force (centripetal force). In a washing machine, the solid walls of the drum provide this inward force on the clothes. When water droplets reach the holes, there is no wall to provide an inward force, so the water continues moving in a straight line (tangent to the drum) because of its inertia.

Anahtar Kavram
In circular motion, centripetal force always acts inward. Objects that lose this inward restraining force will travel in a straight tangential path due to inertia.
