Bellwork:
    1.  A bird traveling at 25 m/s drops its recently caught prey from a height of 400m.  Find the horizontal    
         distance the prey traveled before striking the ground.  How long did the prey fall?  What was its final          vertical velocity before striking the ground.

    2.  A boy tosses a ball to his dad who is 3.5 meters away.  If the ball were thrown with an initial velocity          of 2.5 m/s at an angle of 24 degrees to the horizontal, will the ball land in the dads if it stays in the air          for .22 seconds?
 
Check and go over the homework problems.

Discuss projectile motion and satellites

Study for quiz tomorrow.

Physical Science A

Bellwork:
    1.  State Newton's First two laws of motion.

    2.  Make a list of all the forces we have talked about up to this point and write out all of the formulas.

    3.  What is the acceleration of a 80 kg cart that has a force of 240 N acting on it?

    4.  What happens to the force of gravity between two objects if the distance between them increases?      Decreases?

Objectives:
    1.  List and describe the typical force that you experience and interact with on a daily basis.

    2.  Draw vector diagrams (arrows with magnitudes) that Identifies the magnitude and direction of          everyday forces (e.g., wind, tension in ropes, pushes and pulls, weight).

    3.  Explain how the weight of an object is calculated.

    4.  Explain how air resistance affect a falling object.

Finish the Scavenger Hunt, be sure to find the mass of the objects.  We will go over the answers today in class and go through a few examples of how to solve the gravitational force problems.

Today we will discuss weight and air resistance.

??Will a larger object fall faster than a smaller object??
-Demo to analyze this concept.

HW: Weight Calculations.  Determine the weight/mass of an object in a given situation.  ALSO, finish the calculations for the scavenger hunt

Additional: If you are struggling with remembering the forces, formulas, and concepts, you could make flash cards on quizlet
