content-addressable memory or CAM. Content Addressable Memory provides a performance advantage over other memory search algorithms, such as binary or tree-based searches or look-aside tag buffers, by comparing the desired information against the entire list of pre-stored entries simultaneously, often resulting in an
Sliding Friction. Sliding friction (also called kinetic friction) is a contact force that resists the sliding motion of two objects or an object and a surface. Sliding friction is almost always less than that of static friction; this is why it is easier to move an object once it starts moving rather than to get the object to begin moving from a rest position.
Rolling friction is a force that slows the progress of a ball or wheel once it is already in motion. It can be observed by watching a ball rolling through dirt. After some time, the ball will eventually slow down and stop. Rolling friction is not as strong as sliding friction, which can be helpful in some situations.
