Is force a physical quantity
WebAll physical quantities can be expressed in terms of seven fundamental (base) quantities such as mass, length, time, temperature, electric current, luminous intensity and amount of substance. These seven quantities are called the seven dimensions of the physical world. We can use symbols instead of the names of the base quantities. WebNov 9, 2024 · Yes, a vector quantity, such as velocity, has a magnitude and (unless the magnitude is zero) a direction. To fully specify it, you have to indicate both. But often we only care about one or the other.
