Linear Momentum

Linear momentum is around 10%–20% of your AP test. This unit focuses on how motion is conserved and transferred during collisions. Understanding linear momentum and impulse helps solve problems involving interacting objects.

Now let's get into it!

Descriptive Alt Text
Linear Momentum is the study of how motion is conserved and transferred between objects. In AP Physics C: Mechanics, this unit builds on dynamics by introducing momentum, impulse, and the conservation of momentum principle. It focuses on how forces affect the motion of interacting objects, especially during collisions and explosions. Mastery of linear momentum helps simplify complex problems involving collisions, rebounds, and systems with multiple objects.
