Golden- Motion Test
9/14/15 - Distance, Displacement, Variables, Formulas, Control, Sample Size
Question | Answer |
---|---|
What is Distance? | how much ground an object has covered during its motion. |
What is Displacement? | how far out of place an object is, it is the overall change in position. |
What is an Independent Variable? | what you CHANGE (ex. distance you hold the TV remote). It is the variable that makes one test "independent" of another test. (graphed on x axis). |
What is a Dependent Variable? | the RESULT of the independent variable (ex. is the TV turned on?) . It is what is measured, and depends on what you changed. |
What are Controls? | the things that are kept the same during the entire experiment (ex. how the remote was held or the button being pushed). |
which variable is "the cause?" | Independent Variable |
which variable is "the effect?" | Dependent Variabe |
What is a Scientific Control? | an experiment or observation designed to minimize the effects of variables. |
The object that appears to not be moving is known as.. | Reference Point |
what is motion | when an object changes position. |
speed formula? | speed= distance / time |
velocity? | speed with direction |
