SCHOOL : SMA ---
SUBJECT : PHYSICS
CLASS / PROGRAMME : XI / SAINS
SEMESTER / YEAR : ODD / 2011
MEETING : First
ALLOCATIAON OF
TIME :
2 X 45 MINUTE
COMPETENCY STANDARDS :
1. Analyze the nature
phenomenon and regularity in point object mechanics inclusion
BASIC COMPETENCE :
1.1
Shows the relationship between the concepts of impulse
and momentum to
resolve the collision
INDICATOR OF ACHIEVEMENT :
1. Formulate the concept of impulse and momentum,
the relationship between them, and their application in daily life
2.
Formulate the law of momentum
conservation and its applications
in daily life
3. Integrate the law of
energy conservation and law of momentum conservation for
the collision events
- Learning
Objectives :
Students are able :
1.
Describe the
concept of momentum
2.
Describe the
concept of impulse
3.
Describe the
relationship of
momentum and impulse
4.
Applying a few examples of the
concept of momentum and impulse in daily life
5. Formulate the law of momentum conservation
6.
Applying a few examples of the
legal concept of momentum conservation in daily life
- Learning
Materials :
1.
Sense of
Momentum and Impulse
§
Momentum is the product of the body’s mass and its velocity. The SI unit of
momentum is kg.m/s. The direction of momentum is the same with the direction of
its velocity.
§
Impulse is the product of force and transformation of time or momentum
changing. The SI unit of impulse is N.s or kg.m/s.
I = F.∆t or I = ∆p
2. Law of Momentum Conservation
- Law of Momentum Conservation is
the sum of momentum before collision equals to the sum of momentum after collision
3. Collision
- Completely Elastic Collision
- Completely Inelastic Collision
- Inelastic Collision
D. Learning
