... 1. When the force vectors are in the same direction, they can be replaced by a vector with a length equal to their combined length. 2. If the forces are in opposite directions, the resulting vector is the length of the difference between the two vectors, in the direction of the greater force. 3. Vec ...

1 Equivalent Equations (transposing equations)
... To solve these equations (or even slightly more complicated equations) involves constructing a series of equivalent equations that ends with the equivalent equation “x = solution”. The following steps are required, although steps 1 and 2 are only required for the complicated situations. 1. If you do ...

... Our atmosphere is a giant mixture of gases (a fluid), so it exerts pressure on everything in and around it. An air molecule at a low elevation has a lot of air molecules above it, and their weight is pressing down on it. This means that it is being squeezed into a smaller space and pushed closer to ...
