Properties of Curves
Conclusion of Motion Along a Curve
What happens if we're dealing with a curve with a velocity of constant
magnitude?
Properties of Vector CurvesDistance Along a Curve
Example 1:
Tangents
The unit tangent can be found by:
Example:
CurvatureCurvature is normally represented by the Greek Symbol Kappa, but I'll use a capital K here. Similarly, the radius of curvature is represented by a Greek rho, I'll use a lowercase r. _________ K=0, r is Infinite
K=1/a,
r=a
The concept of curvature comes from fitting a circle tangent to the curve
in at the point of question. When the circle fits just right, the radius
of the circle is defined as the radius of curvature, r, and 1/r is the
curvature, K.
For any curve, the curvature can be calculated using the following formula:
