The maximum number of songs that every iPod is capable of storing varies upon the length of songs, file type, format, and encoding used. Using the iPod to hold photos and videos (when applicable), likewise can reduce the number of songs the iPod can store. However, the capacity of every iPod in gigabytes, along with the Apple estimated number of songs that each can hold, is provided below: iPod Name. Capacity (GB) Estimated Songs.
Friction. Causes of Friction. Friction is a force resisting motion of an object when in contact with another. This resistive force is caused by the surface roughness of the contact area of the materials, molecular attraction or adhesion between materials, and deformations in the materials.
Best Answer: There's a lot of factors. Friction force is equal to mu*N, where mu is the coefficient of friction between the two objects, and N is the normal force, or how hard the objects are pressed together. Three of the biggest factors affecting friction are: 1) The stickiness of the surfaces to one another. This affects the coefficient of friction. 2) The force between the objects; this is the normal force. 3) Whether the objects are already sliding past one another. This also affect the coefficient of friction (static friction vs kinetic friction).
