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.

Mission NL6 Mass vs. Weight

The Question

Determine the weight of a 921-kg car that is moving at a speed of ...

(Note: Numbers are randomized numbers and likely different from the number listed here.)

Formula Fix

The mass of an object is mathematically related to its weight by the equation:
 
Weight = mass • g
 
where g is the acceleration caused by gravity alone. The value of g on Earth is 9.8 m/s/s (approximately 10 m/s/s).

Think About It

The weight of an object is the force of gravity acting upon an object. As the force of gravity, weight is solely dependent upon the mass of the object and the gravitational field strength (more commonly called the acceleration of gravity) of the location where the object at. There are no other factors effecting the weight of the object. The weight of an object is not dependent upon the speed of the object. It is solely dependent upon m and g.
