 Projectile motion can be separated into its components like so:  The equations for projectile motion are:  g is always negative because it points towards the ground which is in the negative direction  to find the range of a projectile   the range is the maximum when the angle of the projectile is at a 45 degree angle therefore,  to find the time it takes to fly the range use equation 4, which, when rearranged gets you , one answer will be zero and it corresponds to before the projectile started moving  to find the maximum height reached  the trajectory, or path the projectile makes can be found using  for circular motion: o even though an object can move in orbit around a point at a constant speed the acceleration is not zero, there is always an acceleration pointing to the center of the circle o the magnitude of this acceleration is o the time (T) it takes to complete a full revolution is the period and can be found by o centripetal acceleration: (explanations and derivations of the formulae)  relative motion basically says that observers moving with respect to each other will describe motion differently o if two observers see a particle move, the relationship between the two observations is: o acceleration is then o these equations are the same no matter what the dimensions it is being viewed from o
