Unit 4 · 4.1 — Linear Momentum

Everything to learn here

• Concept: Linear momentum is a fundamental vector quantity pointing in the exact same direction as an object's velocity vector.
• Concept: For a multi-object system, the total momentum is the vector sum of the momenta of its individual components.
• Equation: $$p=m\cdot v\text{(Linear Momentum definition)}$$
• Vocabulary: Linear Momentum (p) — The product of an object's mass and its velocity, commonly referred to as the "quantity of motion," measured in kg*m/s.
• Skill: Qualitative/Quantitative Translation — Applying positive and negative signs accurately to represent opposing vector directions in 1D collision models.
