Question

Somebody explain the concept of speed please?
Is it abs. value of velocity

Answer 1

is it \[\left| velocity \right|\]

Answer 2

or do you compare acceleration and velocity and see where the signs match up?

Answer 3

Speed is the absolute value of velocity.

\(s = |\vec{v}|\)

Answer 4

The part where you compare the signs of the acceleration and velocity is when determining if the particle/object is slowing down or speeding up.

Answer 5

so they are basically the same thing?

Answer 6

Other than the fact that velocity is a vector and speed is a scalar.

Answer 7

ok thank you
