Objectives:
Terms:
Motion - motion is a change in position of an object in terms of times and revenge point
Motion includes displacement, direction, velocity, acceleration, and time.
Slope - the steepness of a line or altitude.
Displacement - the overall change in the position of an object
Velocity - is a vector measurement of the rate and direction of the change in the position of an object.
Materials:
- Vernier data-collection interface
- Cart
- Lab Quest Device and App
- Motion Detector
- Track, elevated by box
- Vernier dynamics track
Procedure:
1. Connect a motion detector to the Lab Quest.
2. Position the motion detector at the end of the track
3. Elevate the track opposite the motion detector
4. Hold the car 20 cm from the motion detector and zero it
5. Begin collecting data and launch the car up the track. Be sure to stop the car.
6. Compare and label the position vs. time and velocity vs. time graphs
7. Label the car rolling freely up the ramp, the farthest point, and the car moving freely down the ramp on the position vs. time graph
8. On the app, ultitilize the slope instead of the tangent tool

Data Analysis
1. The graphs depicted represent position vs. time and velocity vs. time graphs.
2. Both graphs depict the car being pushed up the track,
3. We discovered we can find the tangent by selecting a section of the graph and utilizing the slope (m= -a/b)
4. The highest point, or fartherest point, is depicted by the peaks on the graphs.
5. Velocity can have a positive or negative value
