如何计算Momentum
learn.whatIsHeading
Momentum is the product of mass and velocity: p = mv. It is a vector quantity (has direction). Conservation of momentum is a fundamental law — total momentum in a closed system is constant.
公式
- p
- m × v — m × v
分步指南
- 1p = m × v
- 2Units: kg·m/s
- 3Impulse = F × Δt = change in momentum
- 4Conservation: m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂' (closed system)
