Factors that determine direction an object will move after an elastic collision?

Click For Summary
SUMMARY

The direction an object will move after an elastic collision is determined by its initial velocities and masses. Specifically, knowing the mass and velocity vectors of the colliding objects allows for precise calculation of their post-collision velocities. This is governed by the principles of conservation of momentum and kinetic energy, which are fundamental in elastic collisions.

PREREQUISITES
  • Understanding of vector mathematics
  • Knowledge of conservation laws in physics
  • Familiarity with elastic collision principles
  • Basic skills in calculating momentum and kinetic energy

Initial velocities and masses of the objects colliding...?

Yes, if they are known then the velocities after collision (which are vectors so include direction) can be determined.
