Lab: Newton's Laws of Motion Assignment:
Reflect on the Lab
1. Throughout the reflection, make sure you have a copy of the Student
Guide and your data tables. Use the drop-down menus to complete the
statements.
In Part I of this experiment, the mass of the car was intentionally manipulated.
This was the independent variable. The dependent variable measured was the
.
In Part II of this experiment, the mass of the car angle of the track was
intentionally manipulated. This was the independent variable. The
dependent variable measured was the .: 1. the 2nd choice
2. the 1st choice
3. the 2nd choice
4. the 1st choice
2. Different measurements are expressed in different units. Choose the
correct SI units for the following types of measurement.
The SI units for measuring the velocity of the car: The SI units for
measuring the acceleration of the car: The SI units for measuring force:
The SI units for measuring mass:: 2nd
3rd
4th
1st
3. What is the average velocity of the car over the first 0.25m? m/s
What is the average velocity of the car over the second 0.25m? m/s: 1. 0.11 2.
0.28
4. The acceleration of the car with the data in the table above would be If the
applied force were cut in half, what do you predict the acceleration would
be?: 1. 0.33
2. 0.17
5. Which arrow represents the force of gravity acting upon the car?Which
arrow represents the normal force on the car?Which arrow represents the
applied force on the car when the driver steps on the gas pedal?: B
A
C
6. Use what you know about mass and how you use it to calculate force in the
following situation: the 3rd choice the 2nd choice
