Question

what is the main difference between (dt) delta time and (triangle time )......in physics....??

Answer 1

Answer:

delta dt refers to differentiation of the quantity.It means that the the quantity would be differentiated with respect to anotger quantity.

While∆t refers to change.(It's a greek alphabet which literally is symbolic if change)

It means that ∆t will tell you the change in time over a certain period.

Like the example here

initial time 3:20 and final time 5:40

so the chnge in time is demonstrated by ∆t between the two times=5:40-3:20=340min-200min=140m

hence ∆t i.e. change in time is =140m

The same applies for ∆v or ∆ d
