Conservation of Linear Momentum

Understanding collisions, impulse, and energy transfer in isolated systems.

Conservation Principle

For an isolated system (no external forces), the total linear momentum remains constant before and after collision.

$$ m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2 $$

Elastic vs Inelastic

Elastic ($e=1$): Kinetic Energy is conserved. Objects bounce off perfectly.
Inelastic ($0 < e < 1$): Some KE is lost to heat/sound.
Perfectly Inelastic ($e=0$): Objects stick together and move with a common velocity. Max KE loss.

Impulse ($J$)

Impulse is the change in momentum experienced by an object during collision.

$$ J = \Delta p = F \cdot \Delta t $$

Set e=0 (Inelastic)

Watch how velocity decreases and Energy Loss maximizes.

Set Equal Masses

If e=1, they will simply exchange velocities perfectly!
