Since the investigative question has two variables, you need to focus on each one separately. Thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? Use the format of "if…then…because…” when writing your hypothesis.
If the mass of an object increases, then its kinetic energy will increase proportionally because mass and kinetic energy have a linear relationship when graphed.
What did you include in your question? Check all that apply.
The dependent variable, the one you measure the response in, is the same for Parts I and II. For both parts of the lab, the dependent variable is .
Now you will focus on a second hypothesis. This hypothesis can be very similar to the first, but this time you want to focus only on the second variable in question, speed. What could be a hypothesis that would illustrate the relationship between speed and kinetic energy? Use the format of "if…then…because…” when writing your hypothesis.
If the speed of an object increases, then its kinetic energy will increase proportionally because speed and kinetic energy have a linear relationship when graphed.
In Part I, the independent variable, the one that is intentionally manipulated, is .
In the example pictured, the soda bottle would act as the .
Which graph represents a nonlinear relationship?
Which statements are part of the safety protocol for this lab experiment? Check all that apply.Always wear safety goggles when performing an experiment.Use caution when dropping objects and/or launching them into the air.Use thermal gloves when handling the soda bottle and beanbag.Use only the materials that your teacher provides or approves.Check the soda bottle and its cap for cracks and chips prior to use.Use only carbonated liquids in the soda bottle.Report all accidents—no matter how big or small—to your teacher.
What did you include in your hypothesis? Check all that apply.
What did you include in your hypothesis? Check all that apply.
In Part II, the independent variable changes to .
The kinetic energy of the soda bottle will be converted into the of the beanbag.
The higher the beanbag rises, the greater the .
