A light meter reports that a camera setting of s at f/5.6 will give a correct exposure. But the photographer wishes to use f/11 to increase the depth of field. What should the shutter speed be?
Free Fall Motion: Moving object are only influenced by gravity Acceleration due to gravity (g) is constant (+9.81 m/s ) o g is always positive o Gravity always pulls objects downward g is independent of mass If there is no resistance, then all object will fall with the same acceleration Object moving upward Object moving downward Acceleration= -g Acceleration=g v = v – gt v v + gt f i f = i 2 2 y f y i +vi – ½ gt yf =y i +vi + ½ gt v f=– igΔy vf=v +2 iΔy
