ch 1:4 slope - know how to calculate slope and know what slope means for a position vs. time gra 1. linear 2. independent variable 3. dependent variable 4. slope 5. speed 6. acceleration a. the variable on the vertical axis (y - axis) b. the slope of a speed vs. time graph. c. the variable on the horizontal axis (x - axis) d. a type of graph that looks like a straight line. e. the measure of the steepness of a line. f. the slope of a position vs. time graph. position vs. time which is the independent variab which is the dependent variabl where was the object at 4 seco find the slope of the graph (n slope=(16 - 4) /... what does the slope you pu ch 2:1 acceleration and average speed - know how to calculate acceleration an speed and velocity and scalar vs. vector quantities. a person starts running from 3 m/s to 9 m/s in 2 seconds. calculate the person’s acceleration. variables: formula: solve: speed (s) or velocity (v) a person walks 3.5 mph. a bird flies 20 m/s. a bike goes 30 m/s toward town. scalar (s) or vector (v) a 50 n force pulls on a rock. 10 meters down the hill. 60 mph toward austin.

Explanation:

Answer:

1. D
2. E
3. A
4. F
5. B
6. C

Variables: \(v_i = 3\ m/s\), \(v_f=9\ m/s\), \(t = 2\ s\)
Formula: \(a=\frac{v_f - v_i}{t}\)
Solve: \(a=\frac{9 - 3}{2}=3\ m/s^2\)
Speed (S) or Velocity (V): S, S, V
Scalar (S) or Vector (V): V, V, V
