Myths And Misconceptions About Gravity - Quiz

Questions and Answers
  • 1. 

    Gravity is down.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Gravity is not always down. While it is true that gravity pulls objects towards the center of the Earth, it can also pull objects towards other celestial bodies or in different directions depending on the circumstances. For example, astronauts in space experience microgravity where they float because they are in a constant state of freefall around the Earth. Additionally, gravitational forces between celestial bodies can cause objects to move in elliptical orbits rather than straight down. Therefore, the statement "Gravity is down" is not always true.

    Gravity exists between all objects that have mass

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Gravity is a fundamental force that exists between all objects with mass. This means that any two objects, regardless of their size or distance, will exert a gravitational force on each other. This force is responsible for the attraction between objects and is what keeps planets in orbit around the sun and objects on Earth's surface. Therefore, the statement that gravity exists between all objects with mass is true.

    There is no gravity in outerspace

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is false because there is gravity in outer space. While the force of gravity is weaker in space compared to Earth's surface, it still exists. Gravity is what keeps celestial bodies, like planets and moons, in orbit around each other. Astronauts in space also experience microgravity, which is a state of apparent weightlessness due to the constant freefall around the Earth. Therefore, the statement that there is no gravity in outer space is incorrect.

    Weight and mass are the same thing

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Weight and mass are not the same thing. Mass refers to the amount of matter in an object, while weight is the force of gravity acting on an object's mass. Mass remains constant regardless of the location, but weight can change depending on the strength of gravity. Therefore, weight and mass are two distinct concepts in physics.

    Black holes suck everything into them.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Black holes do not actually "suck" everything into them. Instead, they have an extremely strong gravitational pull that can capture nearby objects, including light. However, not everything that comes close to a black hole will necessarily be pulled in. Some objects may be able to orbit around the black hole without falling in, depending on their velocity and trajectory. Therefore, the statement that black holes "suck everything into them" is false.

    Heavier objects fall faster

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is known as the Galileo's experiment of dropping two different objects from the same height. According to Galileo's experiment, in a vacuum where air resistance is negligible, objects of different weights or masses fall at the same rate. This means that the weight or mass of an object does not affect its rate of fall. Therefore, the statement "heavier objects fall faster" is false.
