1.6 Momentum

• Momentum


  A measure of a mass in motion, defined as the product of mass and velocity
• Impulse


  A measure of the effect of a force over time, which is also the change in momentum, defined as the product of force and time of force applied
• Momentum


  p = mv
• Impulse


  F∆t = ∆p
• Comparing momentum


  • 7 kg bowling ball at 0.01 m/s
  • 0.003 kg ping-pong ball at 20 m/s
• Momentum is a measure of a mass in motion
• Impulse is a measure of the effect of a force over time, which is also the change in momentum
• Impulse is the product of force and time of force applied
• Momentum is the product of mass and velocity
• Momentum


  F = ∆p/t
• Principle of conservation of momentum: the total momentum in an isolated system is constant, provided no external forces are applied
• Momentum is a vector quantity
