Net Force, Acceleration and Velocity are Vector Quantities. (They have Magnitude and Direction and can be represented with arrows) If the Mass of an object remains constant then the Magnitude of the Net Force and the Acceleration are directly proportional. (When the net force gets bigger, the acceleration gets bigger and vice versa)

The velocity is constant in every horizontal section. Therefore, the velocity is constant in 3 sections: from t=4 to t=8, from t=10 to t=14, and from t=16 to t=20. The velocity is zero in one section, from t=10 to t=14. The area under the curve of a velocity versus time graph represents the total distance moved. Review. Questions

Aug 18, 2011 · In this experiment, the acceleration will be measured as a function of velocity and the data will be used to choose between the two models for the net force and thus the drag force. Coffee filters were chosen because they are light enough to reach terminal velocity in a short distance.
