Acceleration (ACC.A1, ACC.B1)

Acceleration is something everyone has felt, but it can be difficult to describe it accurately. By definition, it is a change in velocity, but the direction of an acceleration is just as important as its magnitude.



The above video aligns with the following standards:

ACC.A1: I can define and calculate acceleration with direction and proper units.

ACC.B1: I can interpret/ draw motion diagrams and graphs for objects moving with changing velocity.

Gaining Information from Graphs (VEL.A1, VEL.C1)

There is a lot of information contained in a graph. When looking at a velocity vs. time graph, the slope is equal to the object's acceleration which we will talk more about in the coming days. And the area under the your plotted line is equal to the displacement of the object. And when the motion of the object is not constant, we can break our graphs into sections and solve its individual parts.


The video above aligns with the Kinematics unit and the following standards:

VEL.A1: I know the difference between position, distance, and displacement and solve problems involving these quantities.

VEL.C1: I can interpret/draw motion diagrams and graphs for objects moving at constant velocity.

Velocity (VEL.B1)

Velocity is nothing more than the rate of change of your displacement from a given point per unit time. We're all familiar with the concept of speed and velocity is similar but with the addition of the direction you are moving in.



The video above aligns with the Kinematics unit and the following standards:

VEL.B1: I can solve problems involving average speed and velocity, and instantaneous speed and velocity.

Scalar vs. Vector (MAT.B1, VEL.A1)

One of the basic tenets of physics is the ability to add and subtract rates of change from one another. In order to do this, we must always be aware of the directions that objects are moving in. The following video will explain how this works with velocities and distances.


The video above aligns with Kinematics unit and the following standards:

MAT.B1: I know the difference between scalar and vector quantities, and can manipulate vector quantities through the use of scaled diagrams, x- and y- components, and angles between vectors.

VEL.A1: I know the difference between position, distance and displacement and solve problems involving these quantities.
