Momentum

Momentum. momentum - property of all moving objects; a vector quantity defined as an object's mass times its velocity from: F = ma F = m D v D t using algebra: F D t = m D v impulse momentum momentum p =m D v units: kg*m/s =m(V f - V i ).

  1. Momentum momentum - property of all moving objects; a vector quantity defined as an object's mass times its velocity from:F = ma F = mDv Dt using algebra:FDt = mDv impulsemomentum momentum p =mDv units: kg*m/s =m(Vf - Vi)

  2. Conservation of Momentum Law of conservation of momentum - total momentum of all objects interacting with one another remains constant. Initial momentum is equal to final momentum. m1v1,i + m2v2,i = m1v1,f + m2v2,f total initial momentum = total final momentum Kinetic energy remains the same. No energy is lost. http://www.walter-fendt.de/ph11e/collision.htm

  3. Conservation of Momentum elastic collisions - a collision between two objects where the objects "bounce off" or remain separate from each other after the collision. m1v1,i + m2v2,i = m1v1,f + m2v2,f http://www.walter-fendt.de/ph11e/collision.htm

  4. Conservation of Momentum inelastic collisions - a collision between two objects where the objects remain "stuck" or connected together after the collision. Kinetic energy is lost to other forms of energy. m1v1,i + m2v2,i = (m1+ m2)vf http://www.walter-fendt.de/ph11e/collision.htm
