• 1.     What factors affect the collision of two objects?

  2.     How can you determine if a collision is elastic or inelastic?

  3.     How can changes in momentum be used to determine the net force applied to an object?

   

• By the end of this unit, students will know: ·         Perfectly elastic collisions of objects moving in arbitrary directions ·         The effect of impulse at an arbitrary angle to initial velocity ·         Inelastic collisions of objects moving in arbitrary directions ·         Collisions: Perfectly elastic, perfectly inelastic, inelastic ·         Conservation of momentum with objects moving in arbitrary directions By the end of this unit, students will be able to: Describe the relationship between impulse and momentum Use conservation of momentum to solve problems Understand the differences between different types of collisions How to find the center of mass of an object
