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.

- What is the total distance of 1 seconds? in meters What is the total distance of 2 seconds? in meters Freely Falling Object
- Consider a car driven along a circular racetrack of radius 1.6 km. What is the magnitude of its displacement after 2.5 laps? What is the total distance traveled?
- Is displacement directly proportional to velocity?
- The position of an object moving along a line is given by #p(t) = 3t - sin(( pi )/6t) #. What is the speed of the object at #t = 2 #?
- If a projectile is shot at an angle of #pi/2# and at a velocity of #22 m/s#, when will it reach its maximum height??
