Phirst Physics

3. The variable that you choose to change; is plotted on the x-axis in a graph
4. A measurement which is close to its 'true' value
6. An suggested explanation for a phenomenon that can be tested
8. The point (0, 0)
11. A measurement which is (approximately) the same when repeated
12. The variable that you measure; is plotted on the y-axis in a graph
16. Famous for his three laws of motion
17. When one variable is changed, another is measured, and all the others are kept constant
18. A straight line on a scatter graph which shows the trend of the results

1. An unexpected measurement which does not follow the trend of the data set
2. The distance by which an object moves downwards when a force is applied to it
5. Makes it easier to read values from a graph
7. A type of relationship between two variables which will produce a straight line through the point (0, 0) in a graph
9. How long it takes a pendulum to complete 'one full oscillation' (to swing back and forth once)
10. Developed the theory of radioactivity
13. What we think will happen in an experiment
14. A type of graph in which there are numbers on both axes and individual points are plotted
15. A variable that is kept at the same value in an investigation
