Recall the word ""speed"". what is speed? what equation(s) do we have for calculating speed? how can we measure the speed of a moving object?

Sagot :

Answer:

Speed = distance traveled / time

Speed is a "scalar" quantity

Velocity = Vector Distance Traveled / time

Velocity is a vector quantity.

Example:

One can travel one lap around a track at some particular speed and his average speed will be (lap distance / time)

However, his vector velocity would be zero because he ended up where he started with zero displacement.
