    1.        What are the major forms of energy?

    2.        What factors does the kinetic energy of an object depend on?

    3.        What is the difference between kinetic and potential energy?

    4.        Describe specific esxamples of energy being converted from one form to another?

    5.        What is the law of conservation of energy and how can it be applied to everyday life?

    6.        What are three modes of heat transfer?


                 Forces and Motion

    1.        How does acceleration differ from speed?

    2.       How can an object’s motion or change in motion be explained using Newton’s Laws of Motion?

    3.       How can the motion of an object be represented on a graph (speed/acceleration)?

    4.       Can the balanced and unbalanced forced of an object be diagramed?

    5.       What are common forces that can affect an object’s motion?

    6.       How are mass and weight different?
