Newton 3

experimental results

You will need to draw two graphs.

The first is F (y axis) against acceleration (x axis).

(Why? Because F=ma)

The second is mass (number of weights) (x axis) against 1/acceleration. (1 divided by the value for acceleration)

You can use excel. There are some sample results below.

Force N	Acceleration (ms-2)
1	1.3
2	1.6
3	1.9
4	2.4
5	2.58
Number of Weights	Acceleration    ms-2
0	1.11
1	0.66
2	0.47
3	0.34
4	0.28
5	0.22
6	0.06

Answers to Physics Questions on the test

This is not a mark scheme. It is a model answer to show you how to answer these type of questions. I have not done this for you to check the marking of your paper. You are to use this to get better at answering examination questions.
