Integrated Physics and Chemistry Unit 6A

Big Idea:

Motion, force, work, and power in everyday life.

Student Expectations:

Priority TEKS

I.4A Describe & calculate an object’s motion in terms of position, displacement, speed, & acceleration.

I.4B Measure & graph distance & speed as a function of time using moving toys.

I.4C Investigate how an object’s motion changes only when a net force is applied, including activities & equipment such as toy cars, vehicle restraints, sports activities, & classroom objects.

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.4E Apply the law of conservation of momentum using action & reaction forces such as students on skateboards.

I.4F Describe the gravitational attraction between objects of different masses at different distances, including satellites.
