Integrated Physics and Chemistry TEKS Correlations
(4) Science concepts. The student knows concepts of force and motion evident in
everyday life. The student is expected to:
(A)calculate speed, momentum, acceleration, work, and power in systems such as in the human body, moving toys, and machines;

During a football game, a 105 kg lineman collides with a 77 kg quarterback. All of the following factors
will determine what will happen during the collision except
A.
B.
C.
D.
the mass of each player
the velocity of each player
the kinetic energy of each player
the gravitational force on each player
This item asks students to look conceptually at momentum. The students need to have a good
understanding of all the factors that affect two colliding objects—and not just be able to plug
numbers into a formula.

The above data was graphed for a carousel. A student studying the carousel data concluded that from 60
seconds to 120 seconds the carousel did not accelerate. The student’s conclusion needs to be revised because
A.
B.
C.
D.
a constant speed only happens if an object accelerates
as the carousel moves it constantly changes direction
moving objects have a constant acceleration
as an object gains speed it accelerates
This is an item that could be coded for TAKS objective 1, since the students are evaluating
a graph. However, they also need to understand the concept of acceleration as a physics
concept, not a layman’s concept. IPC is the first time students begin to look at motion as
vector quantities that have both a direction and speed. This item does not require students to
study vectors per se, but it does require that they have taken an in-depth look at acceleration.

During an investigation, students accelerated boxes using different horizontal forces. They used the force and
acceleration data to determine the mass of the boxes. What is the mass of a box that required a 35 newton
force to accelerate it 1.5 m/s2?
A.
B.
C.
D.
0.04 kg
23.3 kg
36.5 kg
52.5 kg
