Question

F=Dp/dt

what does the d stand for??

Answer 1

differential, infinitesimal increment or linear part of the function. Depends on situation

Answer 2

please explain this to me, ive never taken calculus

Answer 3

in this case the formula is for the change of a momentum of a body, no?

Answer 4

yes!

Answer 5

d stands for small, very small increment of a cuantity:
\[p _{2}-p _{1}=dp\]
when this difference is as small as one whants it to be

Answer 6

so what this formula states is: force aplied to a rigid body is a instantanious (time lap is also very small) change of it's momentum

Answer 7

Or it says "rate of change of linear momentum defines force"

Answer 8

\[F=\frac{\text dp}{\text dt}\]
\(\frac{\text dp}{\text dt} \) is the small change in momentum time changes by a small amount, think of it as the tangent to a curve \(p(t\))

we have to use infinitesimals because the force will change with time

Answer 9

could u just write it as F=p/t ???

Answer 10

this would be average force over a period of time.
