=__**STAAR Reporting Category 2**__ – Force, Motion, and Energy: The student will demonstrate an understanding of force, motion, and energy and their relationships.=


 * **Recognizes** that relationships exist between force, motion, and energy.
 * **Recognizes** the relationship between force and work.
 * **Recognizes** that force and motion are related to potential and kinetic energy.
 * **Knows** that energy can neither be created nor destroyed but changes form

=__**TEKS:**__=

**8.6) Force, motion, and energy.** The student knows that there is a relationship between force, motion, and energy. The student is expected to:

 (A) __**demonstrate**__ and **__calculate__** how unbalanced forces change the speed or direction of an object's motion; **(Readiness)**  (B) __**differentiate**__ between speed, velocity, and acceleration; and (Supporting)

=
 (C) **__investigate__** and **__describe__** applications of Newton's law of inertia, law of force and acceleration, and law of action-reaction //__**such as**__// in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches. **(Readiness) ** =====

**//Review and reenforce the following from previous grade levels://**
 * __(6.8) Force, motion, and energy.__** The student knows force and motion are related to potential and kinetic energy. The student is expected to

(A) compare and contrast potential and kinetic energy; (C) calculate average speed using distance and time measurements; and (D) measure and graph changes in motion.

(C) demonstrate energy transformations such as energy in a flashlight battery changes from chemical energy to electrical energy to light energy.
 * __(6.9) Force, motion, and energy__.** The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form.The student is expected to
 * //Supporting Standard//

(A) contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp, or standing still.
