Question

 Projectile Motion

 1. One day after school, you are enjoying a soda in the back yard. When the can is empty, you decide to throw it in the trashcan. What effects whether or not it gets in the can?

 2. Use Projectile Motion to test your ideas about the things that affect the landing lotion of a projectile.

 Make a complete list of things that affect the landing site of a projectile including your ideas from question #1 and any discoveries you made using the simulation.

 Next to each item, briefly explain why you think the landing location changes.

 Compare your list with another group, discuss your explanations and make modifications

 3. What is meant by the expression "flight path of a projectile"? Draw the flight path of your soda can and describe the shape. Use the simulation to investigate how the items you listed in #2 affect the shape of the flight path. Summarize your discoveries including explanations for the different flight paths.

 4. Suppose your friend asks you to tell them about projectiles. You start to explain, but she interrupts. "Wait," she says, "You're using a lot of words I don't understand. Can you explain in English?" Knowing that a picture is worth a thousand words, you draw a picture of a projectile path and label all the terms that are on the simulation page. Draw a picture like you would for your friend and write what you would tell her about the terms.

 5. Describe why using the simulation is a good method for studying projectiles. Clearly identify the error sources the simulation eliminates or minimizes. Also, run tests to determine how well the simulation represents projectile motion and identify limitations.

Answer 1

1) The factors which decide whether the can gets into trashcan are

(a) force

(b) angle of throw

(c) air resistance ( it's a real life situation)

----------------------------------------------------------------------------------------------------------------

2)

Angle	changes the range and height of projectile
force	changes the range but depends on angle
air resistance	reduces the range
gravity	pulls the can down
acceleration	usually constant in vertical direction but may vary in x direction due to resistance

-------------------------------------------------------------------------------------------------------------------------------

3) Flight path is the path taken by an object launched at an angle under the effects of gravity and other resistance forces.

The typical path will look like

4) same as part (3)
