Learning about levers and how to apply the equations pertaining to their use is one of the more rewarding processes introductory physics offer. It includes a little bit about force and torque, introduces the counter-intuitive but crucial concept of multiplication of forces, and dials you ...
In the end, the reason is simple: I decided to write this post and record a podcast to help out one of my audience members.Here’s what this struggling student wrote:“Hi Anthony. I want to memorize some physics, chemistry, and math formulas, and also some texts that I have to ...
To answer this question, physicists turn their attention to the big bang and the few moments that followed. You might recall that the big bang is the birthing event that gave rise to the universe. You can read more in How the Big Bang Theory Works, but it will be useful to remind you...
First, in the formula moment = I * alpha, what does I represent and how do we calculate it? All the formulas that I've seen are defined as M = Fr. Also, I'm wondering, if, say, two people are playing tug of war, they are leaning back. Why must a pers...
Using this method, the participant narrates their experiences with physics as a river, using metaphorical tools like rafts, rocks, rapids, tributaries to discuss various moments described as twists and turns over time that together amount to a life in physics. We discuss the value of different...
to calculate how long it took for the light to travel out of the hole, to the adjacent mirror, and back through the gap. Another French physicist, Leon Foucault, used a rotating mirror rather than a wheel to perform essentially the same experiment. The two independent methods each came ...
One way to think about how diffuse thinking helps with comprehension and retention is to remember a time you were taking a hot shower and suddenly the flashbulb went on. Having a-ha moments often happen when we’re taking breaks and interleaving encourages them to take place. ...
Suppose you measure the distance between a pair of ocean waves to be 25 feet. You time how long it takes for the wave to pass a pair of reference points and calculate that it's moving about 15 miles per hour. Can you calculate the wave frequency in hertz? The answer is yes, but fi...
In the case of the left and right keys, you're increasing or decreasing the angle property of the player depending on which key is being pressed. Then, in the case of the up key, you're using that angle, along with the thrust property, to calculate the acceleration of the player in ...
The re-cut feature allows creators to pinpoint and isolate the most impactful frames in a video, extending them in either direction to build out a complete scene. This tool is perfect for enhancing key moments, drawing attention to specific visuals, or ensuring a smoother flow between sce...
