Week 6: 12 October to 16 October 2020

11 October 2020:

**No Class:** Columbus Day holiday.

12 October 2019:

**In Class:** Motion in two dimensions.

Expectations: Students will be able to solve problems with motion in two dimensions using vertical components.

**Due:** Pages 1:152-153 (126 – 134).

**Homework:** Pages 1:153-156 (135 – 153).

13 October 2020:

**In Class:** Projectiles Fired at an Angle.

*A*=

_{y}*A*sin θ

*A*=

_{x}*A*cos θ

*A*= Any vector

*A*= Vertical component of

_{y}*A*

*A*= Horizontal component of

_{x}*A*

θ = Angle from

*A*to horizontal

Expectations: Students will resolve a vector into its vertical and horizontal components and solve problems to find range, altitude, and time in the air for projectiles fired at different angles to the ground.

15 October 2020:

**In Class:** Uniform Circular Motion.

*a*=

_{c}*v*

^{ 2}

*r*

*a*= centripetal acceleration

_{c}*v*= velocity or speed

*r*= radius or distance between centers

Expectations: Students will be able to solve problems using the circular motion equation.

**Lab 3:**

Data collection and analysis of
Speeding Cars Lab.

Expectations: Students will be able to use a spreadsheet to analyze distance and time data and to create graphs to find velocity.

**Due:** Pages 1:155-156 (154 – 165).

**Homework:** Pages 1:155-161 (166 – 196).

**Note:** quarter ends 12 November 2021.
