Analogy
Momentum is like tracking a system with arrows and numbers: decide what changes, what stays conserved, and what equation describes it.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Momentum equals mass times velocity.
Momentum is conserved in a closed system.
A longer collision time reduces the force for the same change in momentum.
