Good morning. Bobby, please remind me, what is our current equation for work, the one from AP Physics 1? ♪ Flipping Physics ♪ Work equals F d cosine theta, where F is the force doing the work, d is the displacement of the object, and is the angle between those two vectors. Remember we use the magnitudes of force and displacement in the work equation. (And Bo, what are the units for work?) Newtons times meters or joules. Great. Thanks. Now, it is very important you realize this equation is for the work done by a constant force. We will discuss work done by a non-constant force at a later date, but not today. So, you can look forward to that. Yea! Yea? Yea. Now that we are doing calculus-based physics, we have the r-position vector which identifies the position of an object in 3 dimensions using unit vectors. Therefore we can define the work done by a constant force as work equals force times change in r-position of the object times the cosine of the angle b
