What does it mean for an object to be in free fall?
Only air resistance acting on the object.
Gravity is the only force acting on the obejct.
Any object that is in downward motion.
Define acceleration due to gravity.
The force of gravity acting on an object.
The velocity of an object under the influence of gravity.
The acceleration experienced by an object due to gravity.
The force of gravity.
True or False: Air resistance is the force that opposes the motion of objects through the air.
True
False
True or False: Objects fall to the ground at the same rate because the acceleration due to gravity is the same for all objects.
True
False
