Lab 1: How Fast is it Going?

Vocabulary:

1. Force - a push or a pull on an object

2. Speed - (gone over in class)

3. Constant Speed - the speed of an object remains the same throughout the travel

4. Average Speed - is a number that tells us how fast the car would be moving if its higher speeds and lower speeds were averaged out to a single speed

Analysis questions:

1. Report your calculated speed for each buggy in centimeters per second (cm/s). Compare the speed of the two buggies and determine which buggy traveled with the greatest speed. What does the unit cm/sec mean? (skip 5 lines)
2. How much faster was one buggy moving when compared to the other buggy? Use data to support your answer. (skip 3 lines)

3. How did you determine the speed of the buggy? (skip 3 lines)

4. What were the results of your experiment? (skip 3 lines)

5. A group of astronomers discover that a small meteor has just passed the Moon and is headed straight for Earth. The Moon is 400,000 kilometers away. The astronomers figure the average speed of the meteor is 4 km/s. Using the data from the astronomers, how much time do we have to prepare before the meteor impact occurs? (skip 3 lines)
