Phy 201 & 213 Experiment 2 Fall 2007

Determine average Speed of the Car

1. By measuring time and distance.

The plan:

a. Beginning at a point of origin, you will start the car and drop a bean bag every 5 seconds beside the car's current position.

b. Make a chart with colums for clock reading and location.

c. Plot this data using GA and create new columns delta t, delta x, and velocity = delta x / delta t

Deliverable # 1:

The speed of the car using Graphical Analysis.

2. By using the motion detector and Logger Pro.

Place the motion detector on the floor behind the car .

Start the car and also click collect to start the program.

Use the distance vs time graph to determine the speed.

Use the velociy vs time graph to determine the speed.

Deliverable # 2:

The speed of the car using Logger Pro.
