    Which work equation is accurate?

    • Work=parallel force times the displacement

    • Work=mass times gravity times the displacement

    Correct Answer
    A. Work=parallel force times the displacement
    Explanation
    The correct answer is "Work=parallel force times the displacement." This equation accurately represents the relationship between work, force, and displacement. According to this equation, the work done on an object is equal to the product of the parallel force applied to the object and the displacement of the object in the direction of the force. This equation is derived from the definition of work as the transfer of energy to or from an object by means of a force acting on the object.

    Energy is...

    • The product of the displacement of an object and the component of the applied force that is parallel to the displacement

    • The product of the work of and object and the displacement

    • The ability to do work

    • The ability to belch loudly

    Correct Answer
    A. The ability to do work
    Explanation
    The given correct answer states that energy is the ability to do work. This explanation aligns with the scientific definition of energy, which is the capacity or ability to perform work or exert force on an object. Energy allows objects to accomplish tasks, move, or cause changes in the environment. It is a fundamental concept in physics and is measured in joules.

    A rolling ball is an example of potential energy.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A rolling ball is an example of kinetic energy, not potential energy. Potential energy refers to the energy an object possesses due to its position or condition, while kinetic energy is the energy an object possesses due to its motion. As a rolling ball is in motion, it has kinetic energy, not potential energy.

    Choose the correct equation.

    • KE=(1/2)mgh

    • PE=(1/2)mgh

    • KE=(1/2)mv squared

    • PE=(1/2)mv squared

    Correct Answer
    A. KE=(1/2)mv squared
    Explanation
    The correct equation is KE=(1/2)mv squared. This equation represents the kinetic energy of an object, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object. The equation states that the kinetic energy is equal to half the product of the mass and the square of the velocity. This equation is derived from the principles of classical mechanics and is commonly used to calculate the kinetic energy of moving objects.

  • 6. 

    Choose the correct equation.

    • PE=(1/2)mv squared

    • PE=mgh

    • KE=mg

    • KE=mgh

    Correct Answer
    A. PE=mgh
    Explanation
    The correct equation is PE=mgh. This equation represents the potential energy (PE) of an object, which is equal to the mass (m) of the object multiplied by the acceleration due to gravity (g) and the height (h) of the object. This equation is used to calculate the potential energy of an object based on its position relative to the ground.

    Rate this question:

  • 7. 

    Work is...

    • The product of the displacement of an object and the component of the applied force that is parallel to the displacement

    • The product of the work of and object and the displacement

    • The ability to use energy

    • The ability to double knot a ribbon

    Correct Answer
    A. The product of the displacement of an object and the component of the applied force that is parallel to the displacement
    Explanation
    Work is defined as the product of the displacement of an object and the component of the applied force that is parallel to the displacement. This means that work is only done when a force is applied to an object and it causes the object to move in the same direction as the force. If the force and displacement are not parallel, then no work is done. This definition of work is based on the concept of energy transfer and is commonly used in physics to calculate the amount of work done on an object.
