$projectile motion equations$

#Projectile motion equations free#

These four principles and the four kinematic equations can be combined to solve problems involving the motion of free falling objects. That is, a ball projected vertically with an upward velocity of +30 m/s will have a downward velocity of -30 m/s when it returns to the same height. If an object is projected upwards in a perfectly vertical direction, then the velocity at which it is projected is equal in magnitude and opposite in sign to the velocity that it has when it returns to the same height.This value can be used as one of the motion parameters in the kinematic equations for example, the final velocity ( v f) after traveling to the peak would be assigned a value of 0 m/s. The instant at which it reaches the peak of its trajectory, its velocity is 0 m/s. If an object is projected upwards in a perfectly vertical direction, then it will slow down as it rises upward.If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.(The - sign indicates a downward acceleration.) Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object. An object in free fall experiences an acceleration of -9.8 m/s/s.There are a few conceptual characteristics of free fall motion that will be of value when using the equations to analyze free fall motion.
