Lesson 1: Newton`s First Law of Motion
... A force is a push or a pull upon an object which results from its interaction with another object. Forces result from interactions! Some forces result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) and other forces result from action-at-a ...

Unit 5 Part 1 Simple Harmonic Motion Notes
... No force is acting on the mass when the spring is at equilibrium. If you pulled the mass to the right and then released it (Figure 1a), the spring will apply a leftward force on the object to pull it back to the left. This leftward F on the object will give it a leftward acceleration. This leftward ...
