Integrated Physics and Chemistry Unit 6B

Big Idea:

Motion, force, work, and power in everyday life

Student Expectations:

Priority TEKS

I.4D Assess the relationship between force, mass, & acceleration, noting the relationship is independent of the nature of the force, using equipment such as dynamic carts, moving toys, vehicles, & falling objects.

I.5A Recognize & demonstrate that objects & substances in motion have kinetic energy such as vibration of atoms, water flowing down a stream of moving pebbles, & bowling balls knocking down pins.

I.5B Demonstrate common forms of potential energy, including gravitational, elastic, & chemical, such as a ball on an inclined plane, springs, & batteries.
