Chapter 5 Lecture
... Any reference frame that moves with constant velocity relative to an inertial frame is itself an inertial frame. If you accelerate relative to an object in an inertial frame, you are observing the object from a non-inertial reference frame. A reference frame that moves with constant velocity relativ ...

Unit 1 Lesson 3 Forces
... • In science, a force is a push or a pull. • All forces are vectors. This means they have both a size and a direction. • The unit used to express force is the newton (N). • Forces do not always cause motion. ...
