Physical Science A

Bellwork:
    1.  Explain the controls found within a car that can cause acceleration.

    2.  Consider a situation where a car is traveling around a corner with a constant speed.  Is the car    
         accelerating?  Explain.

    3.  A car takes off from a stop sign and accelerate to a velocity of 45 m/s in a time of 10 seconds.     
         What is the acceleration of the car?

Objectives:
   - Be able to calculate the acceleration of an object given the change in velocity and time.
   - Describe the motion of an object given a velocity vs. time graph.


Go over the acceleration problems using the white boards.  Discuss any difficult problems.

Discuss velocity vs. time graphs.  Begin discussing forces.

HW:  Finish graphing activity

Physics

Bellwork:
    1.  Consider a situation where to students are pushing on a table.  One pushes on the front the other    
    pushes on the side.  Describe the resulting motion of the table as a result of both students.

    2.  If a swimmer were to swim across a river with a swift current, what would the resulting motion of the     swimmer look like?

Collect determining height activity.

Discuss projectiles, projectile motion, and components.

Go over vector problems.

Explain the kinematic formulas using x and y components. 

HW: Finish the projectile motion packet problems.
