## goformit100 2 years ago Is it possible to add a vector quantity to a scalar quantity? Explain.

1. ParthKohli

Nope. You cannot do that, since scalars don't follow vector algebra.

No, only like quantities can be added, so even if both quantities are vectors eg force and acceleration, or both scalars like energy and time, they still cannot be ...

@Eyad Did you forget to credit Wikihow?

4. goformit100

Ok, but is it true can we Multiply or not ?

5. ParthKohli

6. ParthKohli

Yes, we can multiply.

7. ParthKohli

We can multiply a scalar by a vector because multiplying a scalar by a vector is just like adding the vector to itself again and again.

What is the special name given to this perticular theorem then ?

~Wiki answers . @ParthKohli ,Happy ?

10. ParthKohli

It's no theorem.

11. goformit100

ok then what can it be call then ?

12. ParthKohli

It's just... I don't know lol

13. goformit100

Ok Thanks

lets try it $\alpha=6\\ \vec v=\langle1,2,0\rangle$ $\alpha+\vec v=6+\langle1,2,0\rangle=\,?$ $\alpha\times \vec v=6\langle1,2,0\rangle=\langle6\times1,6\times2,6\times0\rangle=\langle 6,12,0\rangle$
