Unit 5: Momentum

Unit 5: Momentum in AP Physics 1 focuses on the concepts of momentum, impulse, and their applications in analyzing collisions and motion.

Momentum (
𝑝
=
𝑚
𝑣
p=mv): A vector quantity defined as the product of an object’s mass and velocity.
Impulse (
𝐽
=
𝐹
Δ
𝑡
J=FΔt): The change in momentum resulting from a force applied over a time interval, represented by
𝐽
=
Δ
𝑝
J=Δp.
Conservation of Momentum: In a closed system, the total momentum before an interaction (e.g., a collision) equals the total momentum after.
