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.
No applied force, no reaction force. There are two types of friction: Static Friction and Kinetic Friction. Static Friction is the frictional force between two objects that are NOT moving relative to each other. It is the initial force that must be overcome in order for things to move. If the force trying to move the object is less than the force of static friction, the object cannot move. Kinetic Friction is the frictional force between two surfaces that ARE moving relative to each other (sliding along each other).
