Physics Chapter 1 Quiz - Quiz


Answer all of the questions in either full sentence or paragraph format depending on what the question specifies.


Questions and Answers
  • 1. 

    Name and explain the first part of the scientific theory.

  • 2. 

    Name and explain the second part of the scientific theory.

  • 3. 

    Name and explain the third part of the scientific theory.

  • 4. 

    Define the difference between a theory and a hypothesis.

  • 5. 

    Science is a cycle of:

    • A.

      Trial and error

    • B.

      Theory and experiment

    • C.

      Cause and effect

    Correct Answer
    B. Theory and experiment
    Explanation
    Science is a cycle of theory and experiment because it involves the development and testing of hypotheses. Scientists propose theories or explanations for natural phenomena, and then design experiments to gather data and test these theories. The results of the experiments either support or refute the theories, leading to the refinement or rejection of the initial hypotheses. This iterative process of theory formulation and experimental verification is at the core of the scientific method, allowing scientists to build knowledge and understanding of the natural world.

    Which of the following is not a metric unit?

    • A.

      Seconds

    • B.

      Gram

    • C.

      Newton

    • D.

      Pound

    Correct Answer
    D. Pound
    Explanation
    The pound is not a metric unit. It is a unit of weight commonly used in the imperial system of measurement. The metric system uses units such as seconds, grams, and newtons to measure time, mass, and force respectively.

    The newton is the metric unit of gravity.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the newton is not a unit of gravity, but rather a unit of force. The newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. Gravity, on the other hand, is typically measured in units such as meters per second squared or newtons per kilogram, depending on the context.

    A psychic conducts seances in which the spirits of the dead speak to the participants. He says he has special psychic powers not possessed by other people, which allow him to "channel" the communications with the spirit. Which part of the scientific method is being violated here?

    • A.

      First

    • B.

      Second

    • C.

      Third

    Correct Answer
    C. Third
    Explanation
    The correct answer is "Third". The third part of the scientific method involves making objective observations and collecting data to support or refute a hypothesis. In this scenario, the psychic's claim of having special psychic powers is not supported by any empirical evidence or scientific data. It is a subjective statement that cannot be tested or verified through observation or experimentation. Therefore, it violates the third part of the scientific method.

    Goethe, a German poet, is less well known for his theory of color. He published a book on the subject, in which he argued that scientific apparatus for measuring and quantifying color, such as prisms, lenses, and colored filters, could not give us full insight into the ultimate meaning of color, for instance the cold feeling evoked by blue and green or the heroic sentiments inspired by red. Was his work scientific?

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    Goethe's work on the theory of color was not considered scientific because it did not rely on empirical evidence or quantitative measurements. Instead, he focused on subjective experiences and emotions associated with different colors, which is not considered a scientific approach.

    A child asks why things fall down, and an adult answers "because of gravity". The ancient Greek philosopher Aristotle explained that rocks fell because  it was their nature to seek out their natural place, in contact with the earth. Are these explanations scientific?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    Yes, these explanations can be considered scientific. While the child's question was answered using a simple explanation of gravity, which is a scientific concept, the ancient Greek philosopher's explanation also offers a scientific perspective. Aristotle's explanation suggests that objects fall due to their natural tendency to seek their natural place, which aligns with the scientific understanding that objects are pulled towards the center of the Earth due to the force of gravity. Therefore, both explanations provide scientific reasoning for why things fall down.

    Buddhism is partly a psychological explanation of human suffering, and psychology is of course a science. The Buddha could be said to have engaged in a cycle of theory and experiment, since he worked by trial and error, and even late in his life he asked his followers to challenge his ideas. Buddhism could also be considered reproducible, since the Buddha told his followers they could find enlightenment for themselves if they followed a certain course of study and discipline. Is Buddhism a scientific pursuit?

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    Buddhism cannot be considered a scientific pursuit because while it may incorporate some psychological explanations of human suffering, it does not adhere to the scientific method. The Buddha's approach of theory and experiment through trial and error does not align with the rigorous and systematic process of scientific inquiry. Additionally, the reproducibility aspect of Buddhism, where followers can find enlightenment through study and discipline, does not meet the criteria of scientific reproducibility which requires independent verification and replication of results. Therefore, Buddhism cannot be classified as a scientific pursuit.

    Physics is the use of the _________ to find out the basic principles governing _____ and ______.

    Correct Answer
    Scientific Method
    Light
    Matter
    Explanation
    Physics is the use of the scientific method to find out the basic principles governing light and matter. The scientific method is a systematic approach used by physicists to investigate and understand the natural world. It involves making observations, formulating hypotheses, conducting experiments, and analyzing data to develop theories and laws. In the case of physics, the scientific method is used to study and explain the behavior of light and matter, including their properties, interactions, and fundamental principles.
