Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

The Question

In order to have work done upon an object, there must be a(n) ____ to cause a(n) ____.

Define Help

Definition of Work:
When a force acts upon an object to cause (or to hinder) a displacement, work is done upon the object. Mathematically, work is the dot product of the force and displacement for such a situation.

Think About It

As the definition of work implies, there are three ingredients of work: force, displacement, and cause. There must obviously be a force acting upon an object; the object must be displaced or moved from its position. And there must be a cause-effect relationship between the force and the motion.
