Term
 Why is motion important?
Definition
 The universe is in motion, from the smallest scale of electrons and atoms to the largest scale of entire galaxies. Motion is all around us.
Term
 How do we describe motion?
Definition
 The mathematical description of motion is called kinematics.
Term
 How do we explain motion?
Definition
 The explanation of motion in terms of its causes is called dynamics.
Term
 What is motion?
Definition
 The change of an object's position in time.
Term
 What are the four basic types of motion?
Definition
 Linear Motion Circular Motion Projectile Motion Rotational Motion
Term
 What are some examples of translational motion?
Definition
 Linear motion, circular motion, and projectile motion.
Term
 When does translational motion occur?
Definition
 Translational motion occurs when the object moves through space.
Term
 What is the object's trajectory?
Definition
 The path along which the object moves, whether straight or curved.
Term
 What is a frame?
Definition
 Each separate image in a motion diagram.
Term
 What is a motion diagram?
Definition
 An image of several layered frames, showing an object's position at several equally spaced instants of time.
Term
 How can we tell if an object is moving at a constant speed in a motion diagram?
Definition
 The images are equally spaced.
Term
 How can we tell if an object is speeding up in a motion diagram?
Definition
 There is an increasing distance between the images.
Term
 How can we tell if an object is slowing down in a motion diagram?
Definition
 There is a decreasing distance between the images.
