Unit 3: Momentum & Impulse Objectives

Objectives

• Focus Questions:
  • How do objects affect each other when they interact?

Knowledge

• Forces between objects cause velocity changes.
• Forces often result from collisions or recoils.
• Interaction time affects force magnitude.
• Impulse causes momentum change: Impulse is proportional to mass times velocity change.
• Momentum is conserved in collisions and recoils.

Skills

• Selecting and using formulas to calculate momentum, impulse, force, final velocity, and time.
• Explaining object interactions (e.g., golf club and ball).
• Drawing and interpreting collision diagrams.

Understanding

• Interacting objects obey the law of conservation of momentum.
