Forces and Motion Essential Questions
Give a brief answer to the following essential questions covered so far in our study of Forces and Motion. You should be able to obtain the answers to these by using your science notebook pages and/or the text.
1. Choosing A Safe Vehicle:
a. What is involved in choosing a safe vehicle?
b. Which vehicle was decided upon as being the safest, why?
c. What type of data was gathered in determining the safest vehicle,
qualitative or quantitative? Give an example
2. Measuring Speed Lab:
a. How can you measure the speed of a moving cart?
b. Why find an average speed rather than just releasing the cart
once and recording the cart’s speed?
c. If a car is traveling 250 miles and is traveling at a speed of 65, what time will the car arrive at its destination if no stops are made? Make sure to write the formula and show your work. Circle your final answer.
b. What type of data was observed in this lab, qualitative or
quantitative, why?
3. Interpreting Motion Graphs Lab:
a. How can you use a graph to describe motion?
c. What two things does the slope of a graph tell us?
d. What does an increasing slope mean?
e. What does a decreasing slope mean?
f. What does a horizontal slope mean?
g. What type of data was observed in this lab, qualitative or
Quantitative, why?
4. Speed and Collision Lab:
a, What is the relationship between speed and collision?
b. Why did the block move further at notch A than at notches B and
C?
c. Find the average speed of the following data? 45.6, 40.8, 49.1,
43.7, 44.5 Show your work.
d. What type of data is the answer in letter c above? Qualitative or
quantitative, why?
