Homework Statement
I am trying to find out if force in Newtons can be negative.
If i know the magnitude of decelaration of a car ( a minus acceleration ) and i know the mass, do i multiply the - acceleration value by the mass, resulting in a minus value in Newtons, or do i multiply the mass by the deceleration, resulting in a positive value in Newtons.
Homework Equations
for example, 1500kg ( mass ) x -2 m s-2 ( acceleration ) = -3000 Newtons
The Attempt at a Solution
I think this would be correct because the minus is telling us the direction in which the force is being applied, but i really am not sure, any advice would be appreciated?
