What is motion?
A change in position over time.
What is linear motion?
All points move the same distance and direction.
What is rectilinear translation?
Linear motion in a straight line.
What is curvilinear translation?
Linear motion along a curved path.
What is angular motion?

What is linear kinematics?
Description of linear motion.
What is position?
An object’s location in space.
What is a reference point?
