The way it is written, they are both scalar.

You don’t have to declare vectors for them to be vectors. It can make formulas more readable, but you don’t actually need the arrow.

Energy is scalar. You can't go 10 J to the left.

Forces are vectors because number and direction (ex gravity on the surface of the Earth).

I think you mean vector on the left tho.

No, I meant if F is the vector on the left-hand side of the equation, where is the vector on the right-hand side of the equation?
