Newton's 2nd law says that when a larger force is applied to an
object of mass m, the object will experience a larger acceleration.
At the same time, you've learned that all objects experience the
same acceleration in a free fall, even if their weights (the forces
of gravity acting on them) are different. That sounds like a
contradiction: on one hand, from the Newton's 2nd law, a larger
force means larger acceleration, on the other hand when applied to...
