Reference Guide & Formula Sheet for Physics Dr. Hoselton & Mr. Price Page 1 of 8 Version 5/12/2005 #3 Components of a Vector if V = 34 m/sec ?48? then Vi = 34 m/sec?(cos 48?); and VJ = 34 m/sec?(sin 48?) #4 Weight = m?g g = 9.81m/sec? near the surface of the Earth = 9.795 m/sec? in Fort Worth, TX Density = mass / volume ( ) 3 unit : kg / m V m ? = #7 Ave speed = distance / time = v = d/t Ave velocity = displacement / time = v = d/t Ave acceleration = change in velocity / time #8 Friction Force FF = ??FN If the object is not moving, you are dealing with static friction and it can have any value from zero up to ? s F N If the object is sliding, then you are dealing with kinetic friction and it will be constant and equal to ? K F N
