Lecture Notes on Momentum and Collisions

These flashcards cover the key concepts related to momentum and collisions, including formulas, laws, and types of collisions.

Conservation of Momentum

momentum can’t be created or destroyed

Newton's 3rd Law

Forces are equal in size and opposite in direction.

Momentum Equation

P = MV.

Impulse

Change in momentum (J = F T)

Change in Momentum

Change in momentum (ΔP) can be calculated as ΔP = Ft.

Elastic Collisions

bounce away (mv+mv=mv+mv)

Inelastic Collisions

stick together (mv+mv=(m+m)v)

Total Momentum in Collisions

momentum stays the same

Types of Collisions

Elastic collisions involve bouncing apart, while inelastic collisions involve sticking together.

Equation for Change in Momentum

The change in momentum can also be expressed as ΔP = m(v₂ - v₁).
