Document Summary

Thus far, the three kinematics equations that describe an objects motion with constant acceleration are as follows. Remember each equation can be derived from the second equation (which we dont need to know how to be able to do for this course) : When an object moves under the force of gravity alone it is called free. Free fall is assumed that there is no effect of air resistance on the fall. downwards motion of an object( because its value is so small, its negligible and doesnt affect calculations) If two object sare dropped from the exact same height, and ir resistance is negated from calculations, they will reach the ground at the same speed, regardless of mass. , and is specially denoted by the symbol g (always a positive value). It should be noted that g is not the acceleration by free fall, but its magnitude.
