Question

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

Answer 1

False: when reporting speed, only value and units are needed, not the direction

Explanation:

Let's start by reminding the difference between speed and velocity:

- Speed is a scalar quantity which tells "how fast" an object is moving, regardless of its direction of motion.

It can be calculated as: follows:

$speed = \frac{d}{t}$

where :

d is the distance travelled

t is the time interval

Therefore, speed has no direction, so it is written only as a value followed by units: for example, 5 m/s.

- Velocity is a vector quantity given by:

$velocity = \frac{d}{t}$

where :

d is the displacement of the object (which is a vector connecting the initial position to the final position of motion)

t is the time interval

Since it is a vector, velocity has both magnitude and direction, therefore it also takes into account the direction of motion of the object. An example of velocity is 5 m/s east, where the direction is also specificied.
