Question

Why terms speed and velocity can be used interchangeably in distance-time graph?

Answer 1

• this this can be calculated under velocity time graph

• speed and velocity both are maintained in SI units

Answer 2

Answer:

You got it wrong.

Speed is the magnitude of velocity

if Speed = 50m/s

Velocity =-50 or +50m/s(Directions)

Remember Speed is a scalar

and Velocity is a vector

Glad if this helps
