Join Steven Lipton for an in-depth discussion in this video Basic physics, part of Advanced iOS App Development: Core Motion.
- [Instructor] When I mention the word physics,…many people get a little nervous.…For our purposes in this course, we are not going to get…deep into physics or calculus to describe motion.…I want to just remind you of a few terms I'll be using…while coding with the Core Motion framework.…Physics is as easy as riding a bicycle.…I'll use a bicycle to help me explain all this.…Speed you are the most familiar with.…It is a ratio of time and distance…which tells you how fast you get from one point to another.…
I can pedal my bike in one minute 360 meters.…In the US, I'd convert that to 13.42 miles per hour.…All our measurements will be in meters per second…unless we convert them.…In Core Motion, we'll describe this speed…as six meters per second.…Velocity is often confused with speed,…but there's an important difference,…velocity has a direction.…My velocity is not six meters per second, that's a speed.…
My velocity on the bike is six meters per second north.…It has the direction north as well as the speed…of six meters per second.…
