We have been working through the Uniform Accelerated Rectilinear Motion (UARM) unit. Here are the big picture questions that I would like you to keep in mind while we’re working through this unit:
- What automobile controls can cause acceleration?
- What is the difference between the common use of the term acceleration and the physics use of the term?
- Suppose that an elephant and a feather are dropped off a very tall building from the same height at the same time. If air resistance is somehow eliminated, which object – the elephant or the feather – will hit the ground first?
- What are the different factors that determine the range of a projectile?
In addition, here is a summary of what you are responsible for in this unit:
|1||Determine the average velocity of an object||UARM test #1||Intro to Acceleration, Graphing Relationships|
|2||Determine the instantaneous velocity of an object||UARM test #1||Intro to Acceleration, Graphing Relationships|
|3||Draw and interpret diagrams to represent the motion of an object moving with a constant acceleration||Moving Man worksheet, Free Fall lab, UARM test #1||Graphing Relationships|
|4||Apply a = Δv/Δt, Δd = v1Δt + ½aΔt and v22 = v1 2 + 2aΔd to solve UARM problems||UARM worksheet, Free Fall lab, UARM test #1||UARM, Free Fall|
|5||Explain the motion of a free-falling body||Free Fall lab, UARM test #1||Free Fall|
|6||Explain the motion of a projectile||Golf Range Assignment, UARM test #2||Graphing Relationships, Projectile Motion|
|7||Determine the position, displacement, or instantaneous velocity of a projectile at a given time||Projectile Worksheet, UARM test #2||Projectile Motion|
