... Sliding friction is a force that opposes the direction of motion of an object as it slides over a surface. Because sliding friction is less than static friction, less force is needed to keep an object moving than to start it moving. Rolling friction is when a round object rolls across a flat floor, ...

We say an object creates a force field throughout the space around it, and this field then touches and exerts a force on objects nearby. We would like the electric field created by a charge ...
