physics.bu.eduaverage velocity can be different from the average speed. EXAMPLE 2.2A – Average velocity and average speed Consider Figure 2.6, the graph of position-versus-time we looked at in the previous section. Over the 50-second interval, find: (a) the average velocity, and (b) the average speed. SOLUTION (a) Applying Equation 2.2, we find that the ...

www.phys.ufl.eduSpeed vs. Velocity • During your 8 mi. trip, which took 15 min., your speedometer displays your instantaneous speed, which varies throughout the trip. • Your average speed is 32 mi/hr. • Your average velocity is 32 mi/hr in a SE direction. • At any point in time, your velocity vector points tangent to your path. • The faster you go ...
Instantaneous Rate of Change — Lecture 8. The Derivative.
pages.uoregon.eduRecall that the average rate of change of a function y = f(x) on an interval from x 1 to x 2 is just the ratio of the change in y to the change in x: ∆y ∆x = f(x 2)−f(x 1) x 2 −x 1. For example, if f measures distance traveled with respect to time x, then this average rate of change is the average velocity over that interval.
