31. Propositions 57 69 deal with the " motion of bodies drawn to one another by centripetal forces ". 32. In these devices, the particles settle out of the slurry under the effects of gravity, or centripetal forces . 33. The centripetal force experienced by the projectile is the accelerating force, and is proportional to the projectile mass. 34. The force acting upon it to pull it toward to axis of rotation is called the centripetal force . 35. For more detail, see centripetal force . 36. You may be interested in centripetal force . talk ) 07 : 48, 9 February 2008 ( UTC) 37. So the net force is inward; that's the centripetal force that keeps the object moving in a circle. 38. The curved motion is maintained so long as this net force provides the centripetal force requisite to the motion. 39. The reason for this is that the normal force is the sum of the tangential force and centripetal force . 40. If the spheres really are rotating, the tension observed is exactly the centripetal force required by the circular motion.
