Newton's 2nd Law of motion
Physics textbook page 95: : Write definition of Newton's second law in to your notebook.
Force is directly proportional to acceleration
Investigation on the effect of increasing resultant force on velocity
- We will share a set of class results for this experiment.
Independent variable: Applied force
Dependent variable: Velocity
Tasks:
1. Write a title, aim, and hypothesis.
2. Draw a results table and ensure it is neat and has a clear and specific title. Units should be in the column headings. Include the same number of decimal places.
3. Complete graphing of results with a ruler. You should do a line graph or a scatter plot with a trend-line.
4. Draw an accurately labelled diagram of your experiment.
5. Explain why there was a slight slope of the table for the experiment.
6. List the controlled variables and with scientific reasoning explain why they make the test fair.
7. Write a discussion of results. How does force affect the average speed? What can you conclude about the acceleration when you increase the force? Refer to Newton's second law in your discussion.
8. Write an evaluation of your results and how the method could be improved. (Find at least 3 sources of error)

Force is inversely proportional to mass.
