  • ___________as the capacity to take some kind of action or make some kind of change.

    energy

  • True or False:

    Energy can only take one form.

    False:

    Forms including heat, light, sound, mechanical, electrical, and chemical energy.

  • True or False:

    Energy forms are either potential or kinetic.

    True

    Both are found in the human body and of equal importance.

  • Kinetic or Potential Energy:

    Stored Energy

    Potential

  • Kinetic or Potential:

    Energy of motion

    Kinetic

  • Example of __________ Energy:

    Putting gas in a car, will remain in the tank while sitting in the driveway. The car is not using energy when it isn't running.

    Potential Energy

  • Example of __________ Energy:

    Kicking a leg

    Movement in molecules creates heat

    Flowing blood

    Sound Waves

    Wind

    Kinetic Energy

  • True or False:

    Kinetic energy is constantly being converted to potential energy.

    Example: Using the car will save energy from being used.

    False:

    Potential Energy is constantly being converted to kinetic energy.

    Example: The gas in the car's tank is waiting to be used in order to go somewhere in that car. The car could not go anywhere without the potential saved in the tank.

  • True or False:

    Food converts into energy.

    True

  • Where does the body get the energy from?

    Food Molecules

  • What is the name of the molecules that captures and stores energy?

    Molecule Adenosine triphosphate or ATP

  • Your cells can use the energy found in molecule to perform particular ______.

    a)electrons

    b) energy

    c) ATP

    d) functions

    Your cells can then use the energy stored in ATP molecules to carry out their particular functions.

  • What two places can excess food store energy?

    a) Kinetic and Potential Energy

    b) Carbohydrates and fat Molecules

    c) Electrons and Protons

    d) Nucleus and Organelles

    b) Carbohydrates and Fat Molecules

  • True or False:

    Potential energy allows an individual to run up a hill.

    False:

    When you put food into your body, and its energy is stored in ATP molecules, you are storing potential energy. When you use that energy to do an activity, such as running up a hill, you are using kinetic energy.
