In this introductory freefall acceleration problem we analyze a video of a medicine ball being dropped to determine the final velocity and the time in freefall. Included are three common mistakes students make. "Why include mistakes?" you might ask. Well, it is important to understand what happens when you make mistakes so that you can recognize them in the future. There is also brief description of "parallax" and how it affects what you see in the video compared to reality.

In this lesson we extend our knowledge of Uniformly Accelerated Motion to include freely falling objects. We talk about what FreeFall means, how to work with it and how to identify and object in FreeFall.

This video starts with a simple acceleration problem and then addresses a commonly held misconception that a negative acceleration always means you are slowing down. I do this by way of examples. Kate (my wife) drove the Prius with a camera suction cupped to the window and videoed me riding my bike several times. In the end I ended up with four different examples on the screen at once and 25 different video layers to describe it all. I am really proud about how well it worked. Enjoy.

This is an introduction to the concept of acceleration. There is also an example problem showing applying the brakes while driving a car in order to avoid hitting a basketball. Also included are common mistakes students make while solving a simple problem like this. It is important to see what those mistakes are because it helps students avoid them in the future.

On March 1, 2014, user Ben Shelton discussed how physics is used in the James Bond movie Skyfall. Since I have seen this movie and other action movies like it, I found it interesting how heroes such as James Bond defy the laws of physics. Ben Shelton broke down the first scene of Skyfall using the equation vf2 = vi2 + 2ad to prove the inaccuracy of a character's fall. It makes me wonder how physics could be used to analyze other action movies. Here is the link to the original post (warning: it contains spoilers):

When taking corners quickly, the biggest worry most drivers should have is slipping and losing control of the car. This happens when a driver takes the corner too fast. The physics of taking a flat corner depends on the equation vmax = Sqrt(mu*r*g). mu, the coefficient of static friction, is constant, as is g, the acceleration due to gravity. Therefore, a driver trying to take a corner as quickly as possible would like to make the radius of the turn as large as possible to allow for a higher vmax, keeping his car from slipping at higher speeds. But how? Doesn't a road have a defined radius?

So my dog just growled and I thought I should do a blog post on her since I cannot think of any ideas. I was just playing fetch with Pearl in my house, which has hard wood floor (the real kind). Pearl ran on the area carpet onto the hardwood, but when she tried to stop, she ended up skidding past the ball into the fireplace (its just a hole in the wall made of brick so she was unharmed). So here's the playbyplay: When Pearl was running on the carpet, she was able to get enough contraction to accelerate forward. Once Pearl hit the hardwood floor, she couldn't accelerate or decelerate as
