1 Direction of acceleration due to gravity vectors

2 Acceleration due to gravity is a vector quantity.
* Acceleration due to gravity is a vector quantity.

3 Vectors can be represented by an arrow to show magnitude and direction

4 On your whiteboards, draw the direction of acceleration for the following objects.
The dashed line represents its path. * not drawn to scale

5 #1. A pebble dropped from a bridge
* Answer

6 #1. A pebble dropped from a bridge
* The vector is oriented down.

7 #2. A baseball tossed up in the air, halfway up the path
* Answer

8 #2. A baseball tossed up in the air, halfway up the path
* The vector is oriented down.

9 #3. A baseball tossed up in the air, at the top
* Answer

10 #3. A baseball tossed up in the air, at the top
* The vector is oriented down.

11 #4. A baseball tossed up in the air, right before it strikes the ground
* Answer

12 The vector is oriented down.
#4. A baseball tossed up in the air, right before it strikes the ground * The vector is oriented down.

13 #5. A football is thrown at a 450 angle, at the top of its path
* Answer

14 #5. A football is thrown at a 450 angle, at the top of its path
* The vector is oriented down.

15 #6. A cannonball rolling off a table
* Answer

16 #6. A cannonball rolling off a table
* The vector is oriented down.

17 What can you summarize about the direction of the vector representing acceleration of all these objects? What are other examples?

18 The rock pebble football and all have different masses
The rock pebble football and all have different masses. How does this affect the magnitude of the acceleration vectors? On Earth, what would its magnitude be?
