# Weight

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

When you think of weight, abbreviated as W or WT, it is probably associated with mass.  But weight is not mass.  Weight is a force on an object accelerated by gravity.  Weight is a vector quantity having magnitude and direction, some of these include acceleration, displacement, drag, force, lift, momentum, thrust, torque, and velocity.

## Weight formula

 $$\large{ W = m \; g }$$

### Where:

 Units English Metric $$\large{ W }$$ = weight $$\large{lbf}$$ $$\large{N}$$ $$\large{ g }$$ = gravitational acceleration $$\large{ \frac{ft}{sec^2} }$$ $$\large{ \frac{m}{s^2} }$$ $$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$
