Calculate position vectors in a multidimensional displacement problem. Solve for the displacement in two or three dimensions. Calculate the velocity vector given the position vector as a function of time.
The video explains the relationship between work and energy, emphasizing that work is only performed when there is both force and displacement in the same direction, calculated using the formula W = F × D. It highlights that maximum work occurs at an angle of 0° between force and displacement, while minimum work occurs at 90°, and negative work happens when force and displacement are in ...
In two (or more) dimensions, you define the average velocity vector as a vector \(\vec v_{av}\) whose components are \(v_{av,x} = \Delta x/ \Delta t\), \(v_{av,y} = \Delta y/ \Delta t\), and so on (where \(\Delta x\), \(\Delta y\),... are the corresponding components of the displacement vector \(\Delta \vec r \)).
