Reading Quiz: Projectile Motion and Vectors

Answers must be submitted by 10 am Wednesday, Dec 12.

Work on the reading quiz INDIVIDUALLY, (on your own).

Read P3 Chapter 4 - Section 1 up to "Subtracting Vectors" + Chapter 7 Section 2 up to "Projectiles Launched at an Angle." Then answer the following questions:

Enter your last name, first initial:  

Click here to indicate that you have read the assigned material and are answering the reading questions on your own.

1.  When we graphically represent a vector using an arrow, the length of the arrow represents what property of the vector ? (one word)

 

2.  When we graphically add two vectors to find a resultant vector, how do we draw the vectors ? (3 words) Choose your answer from the following: “tip-to-tail” (i.e. put the tip of one vector on the tail of the other vector), “tip-to-tip” (i.e. put the tip of one vector on the tip of the other vector), “tail-to-tail” (i.e. put the tail of one vector on the tail of the other vector)

 

3.  Why is it possible to write separate DVAT equations for the vertical and horizontal motion of a projectile ?  (6 words or fewer)

4. What DVAT variable is always the same for both the horizontal and vertical motion of a projectile ? (one word)

 

5. What force is ignored when we model a projectile’s motion ? (2 words)

Study Figures 7-5 and 7-6 and the accompanying text carefully to answer the following questions.

6. In Figures 7-6a and 7-6b, why are the arrows that represent the horizontal velocity at different instants all drawn with the same length ? (5 words or fewer)

7. In Figures 7-6a and 7-6b, why are the arrows that represent the vertical velocity at different instants drawn with increasing lengths ? (5 words or fewer)

8. In Figure 7-6b, what do the arrows that are neither horizontal nor vertical represent ? (3 words or fewer)

9. Imagine you take a sequence of photos (or a movie) of a projectile, like the photos in Figure 7-5 or the motion diagrams in Figure 7-6. Putting the sequence of photos together will give you a picture of the projectile’s trajectory. From this trajectory, how could you tell the direction of the projectile’s velocity at one location along the trajectory ? (5 words or fewer)

10. What is the shape of the trajectory of a projectile ? (1 word)
