Results: These will be your data charts

Construct a data chart similar to the one below for EACH vehicle:

Vehicle Name:____________________________
Trial	Time (s)	Distance (cm)	Velocity or Speed * (cm/s)
1	.	20	.
2	.	20	.
3	.	20	.
4	.	20	.
5	.	20	.
6	.	20	.
7	.	20	.
8	.	20	.
9	.	20	.
10	.	20	.
average	.	20	.
* indicate whether you are measuring speed or velocity for the particular vehicle

 

Discussion:

• Summarize what you did.
• Comment on the difficulties of measuring velocity.
• Was your timing the same for each of the 10 trials?
• For which vehicles could you measure velocity? For which could you measure speed?
• Discuss the differences between speed and velocity.
• Comment on sources of error.
• Suggest improvements

Conclusion: (a one sentence testable statement or a mathematical equation)

Reflection: (personal commentary on what you learned from the activity and/or its application to real life)
