Physics Momentum

Momentum(p)

The quantity of motion an object possesses, calculated as the product of its mass and velocity.

Equation for momentum

p = mv (momentum equals mass times velocity)

Impulse

The change in momentum of an object when a force is applied over a period of time, calculated as the product of the force and the time duration.

recoil

The backward momentum experienced by an object when it discharges or emits another object.

Momentum is what when the net external forces acting on a system is zero?

a conserved quantity

Elastic collision

A collision where both momentum and kinetic energy are conserved, resulting in no permanent deformation or heat generation.

partially elastic collision

inelastic collisison

A collision in which momentum is conserved, but kinetic energy is not, often resulting in permanent deformation and heat generation.

ba

ballistic pendulums

a device used to measure the velocity of a fast-moving projectile.

two dimensional collision

A two-dimensional (2D) collision is when two objects interact and move within a single plane (x and y directions)

center of mass

the point in space where the mass of the entire system is assumed to be located.

Angular momentum

mass moving in a circle. associated with circular motion.

Equation for angular momentum is?

L=mr to the second w
