Position, Velocity, Acceleration

 

This page consists (will consist) of several exercises on learning the relationships between position, velocity and acceleration.

Reference Materials

This documentpdflogo covers fundamental definitions of position, velocity, and acceleration that will be used throughout the course.

 

Video: The Velocity Vector

Here we discover, through the definition of the derivative, that the velocity vector for a particle is always tangent to the particle’s path.

Video: Acceleration Along a Straight Line

When an object is constrained to move along a straight line the acceleration takes on a specific form.

Video: Acceleration Along Curved Paths

When an object moves along a curved path, it experiences a centripetal acceleration perpendicular to the path. The video shows where this acceleration comes from.


Elsewhere, I show you how to quantify this acceleration.
