Physical Science A

Bellwork:
    1.  Explain the difference between speed and velocity.

    2.  What is the time required for a car traveling at 25 km/hr to travel 400 km?

    3.  A rocket travels 2800 km in a time of 20 minutes.  What is the average velocity of the rocket?

    4.  A boat is traveling up a river with current of 3 km/hr, how fast will it appear to travel if the speed-o-    
         meter reads 15 km/hr?

Objectives:
    -Use a graph of distance vs. time to determine the speed of an object.
    -Describe the motion of an object given a distance vs. time graph.

Go over and check the homework.  Pick up a whiteboard!!

Finish discussing speed, velocity, and acceleration.

HW: Answer the book question of pages 40(1-4), 46(1-7), 51(1-5)
**We are having a test over motion on Wed., time to study!!!!****

Physical Science B   

Bellwork:
    1.  What is electricity?

    2.  How is electricity different than an electrostatic discharge? 

Take out homework, we will check and go over the homework.

Discuss voltage, current, and resistance.

Handout and discuss Ohm's Law problems. 

HW: Ohm's Law problems.
