You push an object, initially at rest, across a frictionless floor with a constant force for a time interval, t, which results in a final speed of v for the object. You repeat the experiment, but with a force that is half as large. What time interval is now required to reach the same final speed?
  1. 4t
  2. t
  3. t/2
  4. 2t

Question 2

An object accelerates when it experiences a non-zero net force. Which of the following statements is always true?
  1.The object moves in the direction of the net force.
  2.The object's velocity increases.
  3.The object's velocity is in the same direction as its acceleration.
  4.The object's acceleration is in the same direction as the net force that acts upon it.
