10-9 Newton`s Laws for Rotation
... We’ll spend the rest of this chapter, and a good part of the next chapter, looking at how to apply Newton’s second law in various situations. In Chapter 11, we will deal with rotational dynamics, involving motion and acceleration. For the remainder of this chapter, however, we will focus on situatio ...

... In the absence of external forces, an object at rest remains at rest and an object in motion continues in motion with a constant velocity. What does this statement tell us? 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not i ...

Systems of Masses (slide 8 to 11)
... First, we know that mass m is falling and dragging mass M off the table. The force of kinetic friction opposes the motion of mass M. However, we know that friction is negligible here because it is a smooth surface! We also know, since both masses are connected by a nonstretching rope, that the two m ...

Forces and Motion
... Newton’s First Law: Law of Inertia • Inertia is defined as an object’s tendency to resist any change in its motion. • If an object is moving, it will keep moving at the same speed and direction unless and unbalanced force acts on it. • Example: When you are riding in car, both you and the car are i ...
