Weight is defined as a [[Force|force]] of gravity acting on an object. Weight changes based on location. Weight is measured by a spring balance. Weight is an application of [[Newton's Second Law|Newton's second law]]. mass times acceleration due to gravity (gravitational field strength) ### Symbol $W$ ### SI Unit The SI unit of weight is [[newton]] (N). ### Formula $W = m \cdot g$ Where $W$ is weight $m$ is mass $g$ is acceleration due to gravity ### 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/DAGPwIGCkpk/NCd0O1k3Uikv4wcBEvJQIQ/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]]
