An object drops in free fall. At one instant it is moving at a speed of 50 meters per second. Exactly one second later its speed is about
1) 10 m/s. 2) 50 m/s. 3) 60 m/s. 4) 100 m/s. This is because 5) no net force acts on the object while in its state of free fall. 6) it gains a speed of about 10 m/s for each second of fall. 7) its velocity nearly doubles each second.
