Momentum Impulse Theorem

Definition

The Momentum Impulse Theorem states that when an object experiences an impulse, its momentum changes. Mathematically, it can be expressed as J = Δp = Ft, where J represents impulse, Δp represents change in momentum, F represents applied force, and t represents time.

Analogy

Think of catching a baseball with your bare hand versus catching it with a baseball glove. When you catch it with your bare hand (no glove), you experience a greater change in momentum. But when you catch it with a glove (increased time over which the impact occurs), there is less change in momentum.

Impulse-Momentum Principle: This principle states that the impulse experienced by an object is equal to its change in momentum. It helps explain how forces acting over longer periods can produce smaller changes in momentum.

Conservation of Momentum: This principle states that the total momentum of a system remains constant if no external forces act on it. It is useful in analyzing collisions and explosions.

Elastic Collision: An elastic collision is a type of collision where both momentum and kinetic energy are conserved. In an elastic collision, objects bounce off each other without any loss of energy.
