When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- An object with a mass of #4 kg# is hanging from a spring with a constant of #8 (kg)/s^2#. If the spring is stretched by #8 m#, what is the net force on the object?
- A box with an initial speed of #7 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #1/6 # and an incline of #pi /3 #. How far along the ramp will the box go?
- How can Newton's first law be a consequence of Newton's second law?
- Question below, how does the way someone pushes two boxes affect the action reaction forces on each box?
- How was Newton's first law discovered?
