True
False
The acceleration of an object is inversely proportional to the net force acting on it.
True
False
Air resistance is caused by friction between the air and an object moving through the air.
True
False
The speed of an object dropped in air will continue to increase without limit until it strikes the ground.
True
False
The acceleration produced by a net force on an object is
directly proportional to the magnitude of the net force.
in the same direction as the net force
inversely proportional to the mass of an object
all of the above

the tennis ball
the steel ball
they both have the same force acting on them
