Uniform Circular Motion (CM)
Shape of the trajectory is a given circle (in the xy plane for example)
Speed is constant (given)
For convenience, describe the location on the circle in term
Discussion #2
In this discussion session we will focus on the acceleration vector. Look at the two
vectors below, and .
Since average acceleration is defined as the difference between the two velocity
vectors in some interval of time, we can graphically
1 (a) Figure 1 shows the positions of a bug scurrying along a circular path at successive seconds (i.e., t = 1s).
Determine graphically the average velocities in the intervals between points 0 and 1, 1 and 2, and 2 and 3.
(Remember, vav is r t , and since
Discussion # 4.
As a first exercise you will derive the kinematic equations for motion with constant
acceleration in one dimension. Do not look them up. Do not use your notes. See if
you can derive them on your own. You can do the derivations algebraicall

Since average acceleration is defined as the difference between the two velocity
vectors in some interval of time, we can graphically
Discussion 5: Vector Dot Product and Cross Product
We will soon see that the magnitudes of the force vector and the displacement vector when
multiplied by the angle between the gives us a mathematical definition of WORK. This combination of
two vectors ma
