<u>Explanation:</u>
In research writing, been guided by a cause refers to writing objectively. This objective or cause is usually<em> </em><em>mentioned in the research question or statement of purpose of a research.</em>
For example, a research question may read;
'<em>What is the relationship between body weight and peoples attitudes towards junk food?
'</em>
In the above research question, it becomes clear to readers that the research would be guided towards getting answers to the question-which is the cause.
The dependent variable in the experiment is the time taken for the blocks to hit the ground.
Every experiment must have a dependent variable and an independent variable.
The experiment seeks to determine the effect of changes in the independent variable on the dependent variable. Hence, the independent variable is changed and the effect of this change on the dependent variable is monitored throughout the experiment. In this case, the independent variable is the mass of the blocks while the dependent variable is the time takes the block to hit the ground.
Experimentation is defined as trying something new or testing a theory. One example of experimentation is when trying out new hairstyles. An example of an experiment might be completing a project in a laboratory with test tubes and chemicals to try to better understand chemical reactions. Experiments play an important role in the development of science because they are used to test the reality of thought. Take an axiom or phenomenon that has a rationale and transform it into a law or a theorem like Newton's Law.
