Sorry for the late post. Well, we watched a movie on momentum by the S.S. guy. (SAME SAME!) We were instructed to right down 10 points on what we learned through the instructional movie.
Some 10 points include:
*Momentum: is not mass or inertia; it is (M)(V); how fast something is moving.
*acceleration = (force)/(mass); newtons second law.
*a=(ΔV)/(Δt)
*FΔt=Δmv
*Δ = change in (delta)
*(F)(T)= impulse (Δ momentum)
*if you want momentum to change you change the force.
*3xForce = 3x Momentum
*Reason for pulling elastic band out? Creates a bigger force and longer force making the object travel farther.
*Which canon is more effiecient? The canon that is longer, it has more time, so it goes farther.
*riding w/ the punch both same in dir moes with less spd. is wrong.
*when you pull back ti increases time, so the time of impact is longer.
*bouncing gives alot more momentum.
That is it for now.
