1. The problem statement, all variables and given/known data Force, mass, acceleration 2. Relevant equations F=ma 3. The attempt at a solution Hi I am having a hard time understanding the units of acceleration. Normally I am used to distance/time^2 being the standard unit [ m/s^2 , ft/s^2 ] Now I am seeing this gravity unit [g] being thrown around. Here are 2 examples of simple calculations that use this unit (note highlighted regions of text) http://imgur.com/S14dnYS,oB56WXS http://imgur.com/S14dnYS,oB56WXS#1 **The problem I have is:** If g represents gravity, shouldn't 1.5g = 1.5*32.2[ft/s^2] or 1.5*9.8[m/s^2]. I like doing all my calculations using consistent units and this [g] unit is throwing me off. For example: If you look at yellow highlighted text in the 2nd link above, you will see some person claiming that from F=ma: F = 600lbm x 1.5g = 900lbf ...I feel like this person is incorrect and the F=ma equation should be: F = 600lbm x 1.5 x 32.2 ft/s2 = 28,980lbf.
