True or False??

Answer 1

When reporting the speed, we need to include the value, units and direction the object was traveling.

It is a FALSE

Step-by-step explanation:

Justification :

1. Speed is a scalar quantity.
2. Scalar quantity required only magnitude not the direction.
3. The definition of speed is total distance travelled divided by total time taken to cover that distance.
4. Therefore, speed required value and units not the direction.
5. By velocity which is similar to speed required value, units and direction. And velocity is a vector quantity hence it require direction.
6. For example without speed of a car is 50 m/s. Here 50 is the value and m/s is the unit of a speed.
