Title of the Unit of Study:
Grade 11/12- AP 1 Physics
UNIT #6: Linear Momentum
21st Century Theme: Introduce topic with Discovery channel video on “Understanding Car Crashes’
Whenever two bodies interact, they apply forces on each other, resulting in an Impulse which changes the momentum
of each body. Depending on the severity of the interaction, the interactions may result in catastrophic damage to either
body, hence the physics of collisions and the science of car and sports safety.
CCSS Science and Technical Standards Reading:
RST.1112.1
Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author
makes and to any gaps or inconsistencies in the account. (HS-PS2-1)
RST.1112.7
Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video,
multimedia) in order to address a question or solve a problem. (HS-PS2-1)
CCSS Science and Technical Standards Writing:
WHST.1112.7
Conduct short as well as more sustained research projects to answer a question (including a self-generated
question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on
the subject,demonstrating understanding of the subject under investigation. (HS-PS2-3),(HS-PS2-5)
WHST.1112.8
Gather relevant information from multiple authoritative print and digital sources, using advanced searches
effectively; assess the strengths and limitations of each source in terms of the specific task, purpose, and
audience; integrate information into the text selectively to maintain the flow of ideas, avoiding plagiarism and
overreliance on any one source and following a standard format for citation. (HS-PS2-5)
WHST.1112.9
Draw evidence from informational texts to support analysis, reflection, and research. (HS-PS2-1),(HS-PS2-5
NGSS/Content Standards: PS2-2. Definition of Linear Momentum
Momentum is defined for a particular frame of reference; it is the mass times the velocity of the object. (HS-PS2-2)
PS2-3. Definition of Conservation of Linear Momentum
 If a system interacts with objects outside itself, the total momentum of the system can change; however, any such
change is balanced by changes in the momentum of objects outside the system. (HS-PS2-2),(HS-PS2-3)

Concepts and Skills:
1. Momentum, p = m * v is a vector which measures the mass in motion
2. Impulse is the push a body applies when it interacts when another body applying a contact force, ‘F”, for a contact
time ‘dt”. J = Integral of F.dt
3. During an interaction, impulse applied by the first body results in a change in momentum, J = p, on the second body
4. Momentum is conserved in interactions where external forces can be ignored.
5. Collisions are examples where Conservation of Momentum generally hold to a good level of accuracy
6. Collisions are partitioned into three types, elastic, inelastic and perfectly inelastic depending on whether mechanical
energy is conserved during the collision
Essential Question(s):
1. What is IMPULSE and how does it affect the momentum of a body during an interaction
2. How is momentum transferred during a collision
3. What is conservation of Linear momentum and under conditions does it hold?
4. How can I use Conservation of Momentum to solve Collision problems?
5. How do you differentiate between the 3 types of collisions
Higher Order Thinking Questions:
1. How is conservation of momentum connected and derived from Newton’s laws of Motion
2. Why is conservation of momentum assumed to hold for all Collision?. Is this a valid assumption?
3, How does the principles of conservation of momentum inform how to design safety equipment for cars or sports
uniforms etc.
