The letter p cannot be used because it is reserved for momentum. Position is a [[Vectors|vector quantity]], therefore, direction from the origin is important. It’s possible to have a negative position (by convention this would be left of the origin). Some books may use $\vec{x}$ as the symbol for position. Position is also combined with the [[Time|time]] at which the position is checked. <span style="background:#d3f8b6">This time is shown as a subscript</span>. For example, $x_0$ is the initial time. This initial type is pronounced *x-naught*. Generally the final position does not have a subscript. ### Slide Deck <div style="position: relative; width: 100%; height: 0; padding-top: 56.2500%; padding-bottom: 0; box-shadow: 0 2px 8px 0 rgba(63,69,81,0.16); margin-top: 1.6em; margin-bottom: 0.9em; overflow: hidden; border-radius: 8px; will-change: transform;"> <iframe loading="lazy" style="position: absolute; width: 100%; height: 100%; top: 0; left: 0; border: none; padding: 0;margin: 0;" src="https://www.canva.com/design/DAGPwPfzgb8/jDT-hekdozOkvYIDh73W6A/view?embed" allowfullscreen="allowfullscreen" allow="fullscreen"> </iframe> </div> ### Videos <iframe width="100%" height="480px" style="border:0;" scrolling="no" src="https://go.screenpal.com/player/c06FDpVE6Rc?width=100%&height=480px&ff=1&title=0" allowfullscreen="true"></iframe> <div class="sp-embed-player" data-id="cYfDhxzq4Q"><script src="https://go.screenpal.com/player/appearance/cYfDhxzq4Q"></script><iframe width="100%" height="480px" style="border:0;" scrolling="no" src="https://go.screenpal.com/player/cYfDhxzq4Q?width=100%&height=480px&ff=1&title=0" allowfullscreen="true"></iframe></div> --- Return [[Home|Home]] | [[Mechanics]] | [[Notes Vault/Physics Notes Vault/Kinematics/Kinematics|Kinematics]] | [[Notes Vault/Physics Notes Vault/Kinematics/1D Motion/Position|Position]] | [[Displacement]] | [[Speed]] | [[Notes Vault/Physics Notes Vault/Dynamics/Dynamics| Dynamics]]
