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.
The forces that govern wind velocity include the pressure gradient force, the Coriolis âforceâ (an apparent force due to Earthâs rotation) and friction. The pressure gradient force is what causes the wind to blow. In the atmosphere, pressure differences are a result of changes in density due to warm and cold air. When warm and cold air is close together, we have a pressure gradient.
