Dropping a Ball from 2.0 Meters - An Introductory Free-Fall Acceleration Problem
In this introductory free-fall acceleration problem we analyze a video of a medicine ball being dropped to determine the final velocity and the time in free-fall. Included are three common mistakes students make. "Why include mistakes?"...

Don't Drop Your Camera 5.0 Seconds After Liftoff
An advanced free-fall acceleration problem involving 2 parts and 2 objects. Problem: You are wearing your rocket pack (total mass = 75 kg) that accelerates you upward at a constant 10.5 m/s^2. While preparing to take pictures of the...

The Drop and Upward Throw of a Ball are Very Similar
Previously we determined the motion graphs for dropping a ball from 2.0 meters and throwing a ball up to 2.0 meters and catching it again. In this video I show that the reverse of the drop coupled with the drop itself is the same thing...

Throwing a Ball up to 2.0 Meters & Proving the Velocity at the Top is Zero - An Introductory Free-Fall Acceleration Problem
In the previous lesson we dropped a ball from 2.0 meters above the ground and now we throw one up to a height of 2.0 meters. We do this in order to understand the similarities between the two events. Oh, and of course we draw some...

Graphing the Drop of a Ball from 2.0 Meters - An Introductory Free-Fall Acceleration Problem
This video continues a problem we already solved involving dropping a ball from 2.0 meters. Now we determine how to draw the position, velocity and acceleration as functions of time graphs.

The Humility Soapbox – Uniformly vs. Uniformally
This is much more personal than my average video. I talk about my spelling inadequacies. (yes, i just spelled inadiquacies incorrectly, spell check fixed it, arg.) I use it as a tool to talk about admitting you don't understand as an...

A Free-Fall Problem That You Must Split Into Two Parts
This is a complicated free-fall problem where you have to identify that the velocity at the top of the path is zero in the y-direciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem...

Creating a Position vs. Time Graph using Stop Motion Photography
We talk about a lot of graphs in the theoretical sense. In this video we are actually going to create a position versus time graph in a real sense. By using stop motion photography and stopping a ball at various intervals while falling,...

Common Free-Fall Pitfalls
Yes, there are mistakes that many people make when it comes to free-fall acceleration problems. I dispel many misconceptions and explain both why people think they are true and why they actually aren't. Oh, and there are some special...

Introduction to Free-Fall and the Acceleration due to Gravity
In this lesson we extend our knowledge of Uniformly Accelerated Motion to include freely falling objects. We talk about what Free-Fall means, how to work with it and how to identify and object in Free-Fall. Today I get to introduce so...
