Epsilon(AS) | Physics | Momentum and Collisions | Lesson plan

# Schedule

Jan 11 -18 (1 week)

# Content

• Linear and angular monetum
• Law of conservation of momentum
• Elastic and inelastic collisions

# Instructional objectives

Students should be able to:

• state the principle of conservation of momentum (linear and angular)
• apply the principle of conservation of momentum to solve simple problems, including elastic and inelastic interactions between bodies in

both one and two dimensions

• recognise that, for a perfectly elastic collision, the relative speed of approach is equal to the relative speed of separation
• understand that, while momentum of a system is always conserved in interactions between bodies, some change in kinetic energy may take place
• Understand the term co-efficient of restitution and apply it

# Teaching Process

• Show that the law of conservation of momentum is a consequence of Newton's second law
• Understand that momentum is a clever way of working around forces during a collision
• Understand that momentum= impulse is a cause effect relationship p=fAvg*t and all variables are not equal.
• Using observations of collisions between different masses and tallying observations with theoretical solutions
• working out different collision cases and seeing the importance of using law of conservation of energy.
• Simple references of similarity to angular momentum and its conservation are mentioned along the way

# Activities

• Studying collisions
