2.7: Calculating the Kinematic Quantities of Objects in Constant Acceleration
Topic outline
-
To perform calculations involving objects in constant acceleration situations, such as free fall, we first need to use the basic definitions of velocity and acceleration to derive useful formulas called "kinematic equations".
We can use kinematic equations for any situation where there is a constant acceleration acting on an object (including zero acceleration), and included with this situation is freefall. In free fall, acceleration (a) equals the acceleration due to gravity (g). For an object falling, we use −g to show the vector's downward direction of free fall.
