    Princple of conservation of energy states that energy cannot be created nor destroyed. Energy is transform from one __________ into another.

    Explanation
    The principle of conservation of energy states that energy cannot be created nor destroyed. Instead, it can only be transformed from one form, type, or kind into another. This means that energy can change its manifestation or characteristics, but the total amount of energy in a closed system remains constant.

    A electric dry cell (battery) is used to power a lamp. what energy conversion takes place?

    • Chemical --> electrical energy

    • Chemical --> light energy only

    • Chemical --> electrical energy --: heat and light energy

    • Chemical --> electrical energy --: heat energy only

    Correct Answer
    A. Chemical --> electrical energy --: heat and light energy
    Explanation
    The correct answer is "chemical --> electrical energy --: heat and light energy". When an electric dry cell (battery) is used to power a lamp, the chemical energy stored in the battery is converted into electrical energy. This electrical energy is then converted into both heat and light energy, which are the forms of energy that the lamp emits.

    A 4 kg ball moves with 3m/s. what is its kinetic energy?

    • 12J

    • 36J

    • 18J

    • 9J

    Correct Answer
    A. 18J
    Explanation
    kinetic energy = 1/2 x mass x speed x speed

    Rate this question:

  • 6. 

    A tennis ball 200g is 2.0m above the ground. G=10N/kg. How much gravitational potential energy does the ball have?

    • 4000J

    • 40J

    • 100J

    • 4J

    Correct Answer
    A. 4J
    Explanation
    mgH ; mass must be in Kg! 0.2kg x 10N/kg x 2 m = 4J
