Momentum and Explosions | Physics with Professor Matt Anderson | M9-07

When things explode, there is obviously a lot of energy released. But what about momentum? How does this play into it? Let's take a look.

Excellent good vibes physics lectures!! Making it easy to comprehend.

Greate one! thanks a

Great explanation! Are these videos recordings of a college class? From what university?

[@yoprofmatt]

Yes they are! I'm a professor at San Diego State University in California.
Cheers,

awesome lecture as always! i have 2 questions:
1. can you set the conservation of energy based on the velocities of the objects if you had the magnitudes (not the x and y components)?
so it would be m x vi = m1 x v1 + m2 x v2 + m3 x v3?
2. What if the explosion pushed some of the parts? How would you deal with the individual momentum of the objects assuming that the explosion affected each object with the same magnitude of force?

[@yoprofmatt]

Great questions, thanks.
1) Remember with energy you need speed squared. It looks like you were writing momentum.
2) The explosion will definitely push the parts, but the momentum of the entire system still needs to be conserved.
Hope this helps.
Cheers,
Dr. A

@@yoprofmatt Oh yep, i wrote energy instead of momentum, sorry about that 😅
rephrasing, can you write the conservation of momentum equation using the velocities if they are given to you (not the x and y components, but the total velocity of each object)?
