  • 10. 

    Kinetic energy is the energy of an object in _________ .

    Correct Answer
    motion
    Explanation
    Kinetic energy is the energy possessed by an object due to its motion. When an object is in motion, it has the ability to do work and transfer energy. The faster an object moves, the more kinetic energy it has. Therefore, the correct answer is "motion" because kinetic energy is directly related to the movement of an object.

    Rate this question:

  • 11. 

    The kinetic energy of an object can cause another object to do _________ by colliding and causing it to move a particular ___________ .

    Correct Answer
    work distance
    Explanation
    When an object with kinetic energy collides with another object, it can transfer some or all of its energy to the second object. This transferred energy can then cause the second object to do work, which is the result of a force acting on the object and causing it to move in a particular direction. The distance over which this work is done is known as the work distance. Therefore, the correct answer is "work distance".

    One example of kinetic energy is ______________ energy which is caused by the motion of parts.

    Correct Answer(s)
    mechanical
    Explanation
    Mechanical energy is a form of kinetic energy that is caused by the motion of parts. When objects or systems are in motion, they possess mechanical energy. This energy can be seen in various forms, such as the movement of gears, the rotation of a wheel, or the swinging of a pendulum. The motion of these parts causes them to possess kinetic energy, which is a type of energy associated with movement. Therefore, mechanical energy is a suitable example of kinetic energy caused by the motion of parts.

  • 14. 

    Another example of kinetic energy is ______________ energy which is caused by the random motion of particles of matter.

    Correct Answer(s)
    thermal
    Explanation
    Thermal energy is another example of kinetic energy because it is caused by the random motion of particles of matter. When the particles of matter move faster, they have more kinetic energy, which is manifested as thermal energy. This energy is transferred from one object to another through conduction, convection, or radiation, and is responsible for the sensation of heat.

    Rate this question:

  • 15. 

    An object that has ____________ is not moving or doing work.

    Correct Answer(s)
    potential
    Explanation
    An object that has potential is not moving or doing work. Potential refers to the stored energy in an object or system that can be converted into kinetic energy or work. When an object is not moving or doing work, it means that it is in a state where its potential energy is not being utilized or converted. Therefore, the presence of potential energy indicates that the object is not actively engaged in any motion or work.

    Rate this question:

  • 16. 

    If an object has potential energy, it means that at some point in the past, that object had work performed on it that resulted in energy ____________ .

    Correct Answer(s)
    storage
    Explanation
    If an object has potential energy, it means that at some point in the past, that object had work performed on it that resulted in energy being stored. Potential energy is the stored energy possessed by an object due to its position or state. This energy can be released and converted into other forms, such as kinetic energy, when the object undergoes a change in position or state. Therefore, the correct answer is "storage", as potential energy represents stored energy within an object.

    Rate this question:

  • 17. 

    One example of performing work on an object to give it potential energy is __________ a watch.  As it is being tightened, the spring is gaining potential energy. 

    Correct Answer(s)
    winding
    Explanation
    When we wind a watch, we are applying force to tighten the spring inside it. This action requires work to be done on the object, as force is being applied over a distance. As the spring is being tightened, it gains potential energy. The potential energy is stored in the spring and can be released to power the watch's movement. Therefore, winding a watch is an example of performing work on an object to give it potential energy.

    Rate this question:

  • 18. 

    Winding a watch transofrms _______________ energy to __________ energy.

    Correct Answer(s)
    mechanical potential
    kenetic potential
    rotational potential

    Correct Answer(s)
    potential mechanical electrical
    potential rotational electrical
    potential kinetic electrical
    Explanation
    The potential energy of the water in the tank is transformed into the mechanical energy of the wheel, which is further transformed into rotational energy of the wheel. This rotational energy is then converted into electrical energy.

    Rate this question:

  • 20. 

    Conversion between potential energy and kinetic energy is quite common.  As the potential energy of an object increases, its kinetic energy tends to ____________ .

    Correct Answer(s)
    decrease
    Explanation
    As the potential energy of an object increases, its kinetic energy tends to decrease. This is because potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of motion. When the potential energy increases, it means the object is moving to a higher position or state, which results in a decrease in its kinetic energy as it slows down or loses motion.

    Rate this question:

  • 21. 

    If the kinetic energy of an object increases, its potential energy __________ .

    Correct Answer(s)
    decreases
    Explanation
    When the kinetic energy of an object increases, it means that the object is moving faster. As the object gains more speed and kinetic energy, its potential energy decreases. This is because potential energy is related to the position or height of the object. When the object is moving faster, it is usually lower in height or position, resulting in a decrease in potential energy. Therefore, the correct answer is that the potential energy decreases when the kinetic energy of an object increases.

    Rate this question:

  • 22. 

    A rubber ball held out of a third-story window has potential energy.  If it is released, gravity causes it to fall.  As it falls, it ______________ potential energy because its height decreases.  It ___________ kinetic energy because its velocity is increasing.

    Correct Answer(s)
    loses gains
    Explanation
    As the rubber ball falls from the third-story window, its potential energy decreases because its height decreases. This is because potential energy is directly proportional to the height of an object. At the same time, the ball gains kinetic energy because its velocity is increasing. This is because kinetic energy is directly proportional to the square of an object's velocity.

    Rate this question:

  • 23. 

    A ball is dropped from a third-story window.  When the ball reaches the ground, it has lost all of its ____________ energy (because it cannot fall any further) and at the same time reached a _____________ kinetic energy.

    Correct Answer(s)
    potential maximum
    Explanation
    When the ball is dropped from a third-story window, it starts with potential energy due to its position above the ground. As it falls, this potential energy is converted into kinetic energy, which is the energy of motion. When the ball reaches the ground, it has lost all of its potential energy because it cannot fall any further. At the same time, it has reached its maximum kinetic energy because it is moving at its fastest speed just before hitting the ground.
