<p align="right">Last Update: <font color="#4f81bd">July, 28, 2024</font></p> ## BIG IDEAS - A component of the surface force, the force perpendicular to the surface. - Prevents the object from passing through the surface. - The normal force is a reaction force. - The magnitude of the normal force can vary depending on other forces acting on the object. ### Symbol $F_N \quad or \quad N$ ### SI Unit [[newton]] ### Formula $F_N = mg \ cos(\theta)$ Where $m$ is the mass of the object, $g$ is the acceleration due to gravity, and $\theta$ is the angle ### 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/DAGPwGXKtaQ/gI74xRxSgW47s-ICN6zY3g/view?embed" allowfullscreen="allowfullscreen" allow="fullscreen"> </iframe> </div> ### Related Topics --- [[Home|Home]] | [[Mechanics]] | [[Notes Vault/Physics Notes Vault/Kinematics/Kinematics|Kinematics]] | [[Notes Vault/Physics Notes Vault/Dynamics/Dynamics|Dynamics]] | [[Force]] | [[Net Force]] | [[Newton's First Law]] | [[Newton's Second Law]] | [[Newton's Third Law]] | [[Inertia]] | [[Notes Vault/Physics Notes Vault/Dynamics/Weight]] | [[Normal Forces]] | [[Notes Vault/Physics Notes Vault/Dynamics/Friction]]
