Questions and Answers
  • 1. 

    The power in a mousetrap racer comes from

    • A.

      A trapped mouse that rotates a drive wheel

    • B.

      A mouse pulling the racer with a harness

    • C.

      The spring action of a mousetrap

    Correct Answer
    C. The spring action of a mousetrap
    Explanation
    The power in a mousetrap racer comes from the spring action of a mousetrap. When the mousetrap is set, the spring is compressed and stores potential energy. When the trap is released, the spring rapidly expands, converting the potential energy into kinetic energy. This kinetic energy is then transferred to the drive wheel, causing it to rotate and propel the racer forward. The trapped mouse and the mouse pulling the racer with a harness are not mentioned as sources of power in the given information.

    Rate this question:

  • 2. 

    Which of the following is NOT commonly used as a wheel for the racer.

    • A.

      A cookie

    • B.

      A compact disc

    • C.

      A wheel from a remote control car

    Correct Answer
    A. A cookie
    Explanation
    A cookie is not commonly used as a wheel for a racer because it lacks the necessary structure and durability to function effectively as a wheel. While a compact disc and a wheel from a remote control car are both commonly used as wheels for racers due to their circular shape and ability to rotate smoothly, a cookie would not be able to provide the same level of stability and traction required for racing.

  • 3. 

    When this is pulled on a mousetrap racer, it will cause the wheels to turn.

    • A.

      A shift lever

    • B.

      The length of string

    • C.

      The piece of wood from the body

    Correct Answer
    B. The length of string
    Explanation
    When the length of string is pulled on a mousetrap racer, it causes the wheels to turn. The tension created by pulling the string activates the mousetrap mechanism, which in turn releases the stored energy and propels the racer forward. The length of the string determines the distance over which the tension is applied, thus affecting the speed and movement of the wheels.

    Rate this question:

  • 4. 

    The body of a mousetrap racer should be made from something that is ________.

    • A.

      Strong such as thick plate steel

    • B.

      Light things such as balsa wood or poster board

    • C.

      Flexible such as construction paper

    Correct Answer
    B. Light things such as balsa wood or poster board
    Explanation
    The body of a mousetrap racer should be made from light materials such as balsa wood or poster board. This is because a lighter body will allow the racer to move faster and cover more distance. Using strong materials like thick plate steel would make the racer heavier and slower. Similarly, using flexible materials like construction paper may cause the body to deform or bend, affecting the overall performance of the racer. Therefore, opting for light materials ensures a better balance between strength and speed.

    Rate this question:

  • 5. 

    A mousetrap racer can have four, three or even just two wheels.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A mousetrap racer can have four, three, or even just two wheels because the number of wheels on a mousetrap racer is not fixed. The design and number of wheels can vary depending on the preferences and requirements of the builder. Some racers may have four wheels for stability and balance, while others may have three or two wheels for simplicity or specific performance advantages. Therefore, it is true that a mousetrap racer can have four, three, or even just two wheels.

    Rate this question:

  • 6. 

    The wheels on a mousetrap racer rotate on the _____.

    • A.

      Axles

    • B.

      Ball bearings

    • C.

      Retaining bar

    Correct Answer
    A. Axles
    Explanation
    The wheels on a mousetrap racer rotate on the axles. Axles are the cylindrical rods or shafts that connect the wheels to the body of the racer. They allow the wheels to spin freely and smoothly, enabling the mousetrap racer to move forward. The axles provide stability and support to the wheels, ensuring that they rotate in a controlled manner and effectively transfer the force generated by the mousetrap to propel the racer forward.

    Rate this question:

  • 7. 

    An important thing to consider when building a mousetrap racer is _____.

    • A.

      Keeping the weight down by using lightweight materials

    • B.

      Keeping the mousetrap well oiled

    • C.

      Putting warning stickers near the dangerous parts

    Correct Answer
    A. Keeping the weight down by using lightweight materials
    Explanation
    When building a mousetrap racer, it is important to keep the weight down by using lightweight materials. This is because a lighter racer will have less mass to overcome inertia and will be able to move faster. Using lightweight materials such as carbon fiber or aluminum can help reduce the overall weight of the racer, allowing it to achieve higher speeds and better performance.

  • 8. 

    It is best to use skinny wheels on a mousetrap racer to ____.

    • A.

      Be able to sneak up on opponents

    • B.

      To use up materials

    • C.

      Reduce rolling resistance

    Correct Answer
    C. Reduce rolling resistance
    Explanation
    Using skinny wheels on a mousetrap racer helps to reduce rolling resistance. Rolling resistance is the force that opposes the motion of an object rolling on a surface. By using skinny wheels, the contact area between the wheels and the surface is reduced, resulting in less friction and resistance. This allows the mousetrap racer to move more smoothly and efficiently, increasing its speed and performance.

    Rate this question:

  • 9. 

    The main part that puts the racer in motion is the ____.

    • A.

      Spring

    • B.

      Cheese

    • C.

      Car body

    Correct Answer
    A. Spring
    Explanation
    The spring is the main part that puts the racer in motion. Springs have the ability to store potential energy when they are compressed or stretched, and when released, this potential energy is converted into kinetic energy, causing the racer to move forward.

    Rate this question:

  • 10. 

    When the mousetrap racer is moving, what energy is it using?

    • A.

      Kinetic

    • B.

      Potential

    Correct Answer
    A. Kinetic
    Explanation
    The mousetrap racer is using kinetic energy when it is moving. Kinetic energy is the energy of motion, so when the racer is in motion, it is using this energy to propel itself forward.
