Focus: Students will investigate the law of conservation
of linear momentum.
CONTENT AREA: Science
GRADE LEVEL: 11, 12
TOPIC: Physics, conservation of linear momentum
CONTENT OBJECTIVE(S):
-
The student will predict the outcome of 1 dimensional elastic collisions.
-
The student will run an online simulation of a 1 dimensional elastic collision.
-
The student will predict the outcome of a 1 dimensional perfectly inelastic
collision.
-
The student will run an online simulation of a 1 dimensional perfectly
inelastic collision.
-
The student will describe the motion of the center of gravity of a system
of particles undergoing collisions.
SUBJECT AREA TEKS:
§112.47. Physics.
(c) Knowledge and skills.
(1) Scientific processes. The student, for at least 40%
of instructional time, conducts field and laboratory investigations
(2) Scientific processes. The student uses scientific
methods during field and laboratory investigations.
The student is expected to:
- organize, analyze, evaluate, make inferences, and predict trends
from data;
- communicate valid conclusions;
(3) Scientific processes. The student uses critical
thinking and scientific problem solving to make informed decisions. The student
is expected to:
- analyze, review, and critique scientific explanations, including hypotheses
and theories, as to their strengths and weaknesses using scientific
evidence and information;
- express laws symbolically and employ mathematical procedures including
vector addition and right-triangle geometry to solve physical problems;
(4) Science concepts. The student knows the laws
governing motion. The student is expected to:
- identify and describe motion relative to different frames of reference.
(5) Science concepts. The student knows that changes
occur within a physical system and recognizes that energy and momentum
are conserved. The student is expected to:
- calculate the mechanical energy and momentum in a physical system
such as billiards, cars, and trains.
- demonstrate the conservation of energy and momentum.
TECHNOLOGY TEKS:
Using internet technology and java applets
RESOURCES/MATERIALS:
-
Internet (computer lab or library)
LESSON PROCEDURE: Students will get online and go to the Physics
Class Web site. From there, they will click on the 3rd 6
weeks link and then click on the Collision Demo link. Follow
the instructions on the simulation. Change mass and initial velocity. See
if you can calculate final velocities. Change coefficient of restitution
( eta ). See what happens. Change the frame of reference. Is momentum conserved?
