Momentum and Impulse Lecture Review

These flashcards cover key concepts related to momentum and impulse as discussed in the lecture, providing definitions and formulas important for understanding the topics.

Momentum

The quantity of motion an object has, defined as the product of mass and velocity.

Impulse

The product of the applied force and the duration of time over which the force is applied, used to change an object's momentum.

Weight of Momentum

The principle that the more momentum an object has, the harder it is to stop.

Impulse-Momentum Theorem

The theorem stating that the impulse applied to an object is equal to its change in momentum.

Elastic Collision

A collision where both momentum and kinetic energy are conserved.

Inelastic Collision

A collision where momentum is conserved, but kinetic energy is not, as it is transformed into other forms of energy.

Law of Conservation of Momentum

The principle stating that the total momentum of a closed system remains constant before and after a collision.

Formula for Impulse

I = F × t, where I is impulse, F is force, and t is the time over which the force is applied.

Formula for Momentum

p = m × v, where p is momentum, m is mass, and v is velocity.

Final Velocity in Collisions

In a closed system, the final velocity of combined objects after a collision can be calculated using the formula m1v1i + m2v2i = (m1 + m2)vf.
