Tori heard an observation from a student in class stating that drinking body armor hydrates you after a workout better than water or Gatorade. After some research, she makes the assertion that Body Armor hydrates you more than any other sports drink or just plain water. She then begins to design her experiment. Match the parts of the experiment to the experiment she plans to conduct.

What was the position of object A after 6 seconds?
What was the position of object B after 2 seconds?
What was the velocity of object A?
What was the velocity of object B?
Create a Motion Map from scratch to fit the following situation:
The ball rolled backward at 2m/s for 3s. It then stopped for 6s. And then the ball traveled forward at 6m/s for 2s.
Describe what occurred within the following Position vs Time Graph
Draw and label the graph of the three different scenarios with three different colors.
You sat 11 meters away from the starting line.
You ran at 5m/s for 3 seconds
You ran at 3m/s for 2 seconds, stopped for 1 second, then continued running at 3m/s
What is the objects average speed?

Consider the position-time graph. Each one of the three lines on the position-time graph corresponds to the motion of one of the three cars. Match the appropriate line to the particular color of the cars in problem #1.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
green | arrow_right_alt | B |
red | arrow_right_alt | A |
blue | arrow_right_alt | C |
The velocity-time graph for a two-stage rocket is shown below. Use the graph and your understanding of slope calculations to determine the acceleration of the rocket during the listed time interval.
What is the acceleration of the rocket from t=9 -> t=12 ?
What is the graphical interpretation of the motion of the car?
What is the graphical interpretation of the motion of the car?
Demonstrate 'freefall' on a position vs. time graph and on a velocity vs. time graph.
REVIEW: Look at the distance-time graph below.
What is the acceleration of the object?
What is acceleration? Type a definition for this term in your own words.
Describe the acceleration.
Acceleration due to gravity ...
What was the speed of the ball when it hit the ground below the cliff?
What is the distance of the ball above its initial position when it reaches the peak?
A 2-kg object is moving horizontally with a speed of 4 m/s.
How much net force is required to keep the object moving at this speed and in this direction?

A leftward force is applied to a dresser to accelerate it to the left across the bedroom floor. Ignore air resistance. (Grading on forces and magnitudes)
Why does constant velocity indicate NO net force?
What is the net force on the object?
Explain what is happening to the object using the word 'acceleration'.
A rightward force is applied to a 10-kg object to move it across a rough surface at constant velocity. The coefficient of friction between the object and the surface is 0.2. Use the diagram to determine the gravitational force, normal force, applied force, frictional force, and net force. (Neglect air resistance.)
Explain what is meant by 'terminal velocity.'
