    ijl, A fmall portion of the earth’s furface is a plane. 2d, All bodies defcend, or fall to the earth’s furface, in lines parallel to each other. 3d, The fame body is of the fame weight at different heighths from the earth’s furface. Simple motion is that which is produced by a frngle force. Compound motion is that which is produced by two or more forces a&ing conjundtly at the fame time. Simple motion produced by a momentary im- pulfe is uniform. Suppofmg, F = the force producing the motion, v = velocity, t = time Ipent during the motion, s - the fpace paffed over, Qj= the quantity of main ter in the body *, in uniform motion we have the following general propofitions : 1. v ^F, when the quantity of matter in the moving body is given. 2. s == t, when the velocity is given. 3. s == v, when the time is given. 4. s 4 tv. 5. F == C>, when the velocity is given. 6. F 4= Qy. A
