A scalar is a measure of something that has only a magnitude to define it. A 10 meter length of cable is sufficient to define the length, whether we move it 2 meters to the left or 5 meters to the right. Also, 30 seconds is a scalar, and so are 25 degrees Celsius, and 30 liters. The magnitudes of these quantities are all that are needed to define them. Maybe to better understand that, we need to…
