DAY 35

WARM-UP

Practice adding vectors tip to tail. Draw a set of axes, draw the vectors, then draw the resultant

1. Combine these two vectors: 5N due north (0*) and 10N due south (180*)

2. Combine these two vectors: 5N due north (0*) and 5N due south (180*)

3. Combine these two vectors: 5N due north (0*) and 10N due west (90*)

4. Combine these two vectors: 5N due north (0*) and 5N due west (90*)

Answer/Complete:

0. What is the motion of an object with no net force acting on it?

1. 0:31 Define Newton's 1st law

2. 2:18 How does Mrs. Zeller's FBD show that there is no net force on the rock? Copy her sum of forces equation.

3. 2:18 In the rock example, the rock is at rest. Does that mean there are no forces on the rock? If not, what does it mean?

4. 2:51 In the ball bearing example, the ball bearing is moving. Does that mean there is a net force on the ball? If not, what does it mean?
