Collisions
Conservation of momentum
m1v⃗i1+m2v⃗i2=m1v⃗f1+m2v⃗f2m_1\vec{v}_{i1} + m_2\vec{v}_{i2} = m_1\vec{v}_{f1} + m_2\vec{v}_{f2}m1vi1+m2vi2=m1vf1+m2vf2
Both momentum & kinetic energy conserved
Separate cleanly
Momentum conserved, KE not conserved
To heat, sound, or deformation energy
Objects stick together, move with same velocity
Vector - direction matters
Elastic: p & KE; Inelastic: p only
