Momentum momentum property of all moving objects a

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

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. m 1 v 1, i + m 2 v 2, i = m 1 v 1, f + m 2 v 2, f total initial momentum = total final momentum Kinetic energy remains the same. No energy is lost. http: //www. walter-fendt. de/ph 11 e/collision. htm

Conservation of Momentum elastic collisions - a collision between two objects where the objects "bounce off" or remain separate from each other after the collision. m 1 v 1, i + m 2 v 2, i = m 1 v 1, f + m 2 v 2, f http: //www. walter-fendt. de/ph 11 e/collision. htm

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. m 1 v 1, i + m 2 v 2, i = (m 1+ m 2)vf http: //www. walter-fendt. de/ph 11 e/collision. htm

Elastic or inelastic?

Now you give me two problems for inelastic and two for elastic. • Include a word problem and diagram as well as the solutions. You can pair up. Be creative! EXTRA POINTS FOR EXTRA IMAGINATION!
