Question

Is energy a vector quantity?

Answer 1

Scalar and Vector quantity

1. A scalar quantity is one that has no direction and just has a magnitude.
2. A vector quantity is one that has both a magnitude and a direction.

Energy

1. We can define energy as the work done by the body.
2. Energy has magnitude but not direction. Therefore it is a scalar quantity.
3. We generally call energy work done by the body.

Step3: Energy formula

$W=\overrightarrow{F}\times \overrightarrow{d}[whereW=workdone,F=force,d=displacement]$

Energy is not a vector quantity. It is a scalar quantity, as it has magnitude only.
