Momentum or inertia in motion, is what we are learning in unit 7. Momentum is the mass of an object multiplied by the velocity the object is moving at, this is the equation we learned and used today:
∆p = m(￫v)
- ∆p = total momentum = units: kg x m/s
- m = mass = units: kg
- ￫v = velocity (￫ means it's a vector) = units: m/s
Like velocity, there is an initial momentum pin and a final momentum. When an object collides it will start and end with the same momentum, because momentum is conserved. Conserved means to maintain (a quantity such as energy or mass) at a constant overall total, so momentum stays constant.
Nice use of the right symbols in each equation. How did you get the delta triangle and the small arrow? That's a nice look, instead of putting something like "change in P = ~~~~~"
ReplyDeleteVery important equations thanks for showing them to me again! Also i was wondering the same thing as Sean :)
