Early in Lesson 1 it was mentioned that there are a variety of means of describing the motion of objects. One such means of describing the motion of objects is through the use of graphs - position versus time and velocity vs. In this part of Lesson 5, the motion of a free-falling motion will be represented using these two basic types of graphs. Observe that the line on the graph curves. As learned earlier , a curved line on a position versus time graph signifies an accelerated motion. A further look at the position-time graph reveals that the object starts with a small velocity slow and finishes with a large velocity fast. Since the slope of any position vs. Finally, the negative slope of the line indicates a negative i. Observe that the line on the graph is a straight, diagonal line. As learned earlier, a diagonal line on a velocity versus time graph signifies an accelerated motion.

We are here probably considering a small sphere falling slowly through a viscous liquid, with laminar flow around the sphere, rather than a skydiver hurtling through the air. In the latter case, the airflow is likely to be highly turbulent and the resistance proportional to a higher power of the speed than the first. The equation of motion is. To obtain the first time integral, we write the equation of motion as. In the middle of an exam, while covering this derivation that you know so well, you can suddenly find yourself in inextricable difficulties. The thing to note is this. If you look at the left hand side of the equation, you will anticipate that a logarithm will appear when you integrate it. Keep the denominator positive! Some mathematicians may know the meaning of the logarithm of a negative number, but most of us ordinary mortals do not - so keep the denominator positive! Students will have seen equations similar to this before in other branches of physics - e.
