Physical Quantity Quantity Symbol Used for Unit abasement A Measure of sustained displacement: the first integral with respect to time of displacement m ⋅ s Absorbed dose rate D Absorbed dose received per unit of time Gy/s Acceleration a → Rate of change of velocity per unit time: the second time derivative of position m/s 2 Action S Momentum of particle multiplied by distance travelled J/Hz Angular acceleration ω a Change in angular velocity per unit time rad/s 2 Angular momentum L Measure of the extent and direction of an object rotates about a reference point kg ⋅ m 2 /s Angular velocity ω The angle incremented in a plane by a segment connecting an object and a reference point per unit time rad/s Area A Extent of a surface m 2 Area density ρ A Mass per unit area kg ⋅ m −2 Capacitance C Stored charge per unit electric potential farad (F = C/V) Catalytic activity concentration Change in reaction rate due to presence of a catalyst ...
Teacher collaboration occurs when members of a learning community work together to increase student learning and achievement. If our ultimate destination as educators is student achievement, think of teacher collaboration as the journey. Collaboration is not a task to complete then move on, it’s an ever-changing, ongoing process that is only enhanced by social networks and access to new technology.
