Question

Are work and force both represented by vectors?

Answer 1

I know force is

Answer 2

@amistre64

Answer 3

how do we define work?

Answer 4

W=Fd

Answer 5

so a vector, times a scalar is a what?

Answer 6

work is a scalar

in vector terms, it is the dot product of force and displacement, both vectors\[W = \vec F \bullet \vec x\]

Answer 7

i spose we should have defined "d" as well

Answer 8

scalar times a vector = a vector?

Answer 9

yeah, google says F adn d are vectors, Irish has it

Answer 10

So work is the sum of the two vectors? It individually is not?

Answer 11

not the sum, the inner prouct (dot product)

Answer 13

Alright thank you both :)

Answer 14

its confusing when we first see the Work formula since d is often defined as distance, instead of displacement.

Answer 15

Thats what i thought as well
