• How can you describe the position of a point moving along a cycloid using parametric equations?
• How can you find the position vector of a moving point?
• How can you find the velocity of a moving point using vectors?
• What is the formula for vector acceleration?
• How can you find arc length using vectors?
• What is the arc length formula in Calculus?
• How do you find the length of an arch of a cycloid?
• What is a unit tangent vector?
• What does Kepler's second law have to do with vectors?
This lesson is all about velocity and acceleration of moving particles, picking up from where the previous video left off with parametric equations and cycloids. Obviously, speed and acceleration are important concepts in Calculus, so this lesson is quite important. Also, a very interesting application using Kepler’s second law is explained in this lesson.
