Unit 2: Velocity and Acceleration

Major Concepts of Unit

• Understand how to create and interpret velocity vs. time graphs

• Understand and apply the concept of acceleration

• Be able to identify when there is and is not an acceleration in regards to velocity (not speed)

• Understand how the relative directions of acceleration and velocity causes something to speed up or slow down

• Understand how to calculate the acceleration from a velocity vs. time graph (take the slope)

• Understand how to calculate displacement from a velocity vs. time graph (area)

• Understand how to calculate acceleration from its definition

• Understand the limitations of d = vt

• Understand the derivation of the three kinematic equations for constant acceleration

• Understand how to use the three kinematic equations for constant acceleration to solve for displacement, initial velocity, final velocity, time or acceleration.
