Physics 101 Introduction to College Physics Lesson 10 Fundamental Laws of Motion

Introduction Lesson Over View Objective; State and discuss Newton’s laws of motion. Preview Force 1 st, 2 nd and 3 rd Laws Application Practice

Force Preview push or pull exist as a result of an interaction Types –contact forces, (frictional, tensional, normal, air resistance, and applied forces ) –forces resulting from action-at-a- distance (gravitational, electric and magnetic forces) Back

First Law of Motion Law of Inertia Every object in a state of uniform motion or rest tends to remain in that state of motion or rest unless an external force is applied to it. View Illustration

Second Law of Motion View Illustration Acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.

Third Law of Motion For every action, there is an equal and opposite reaction View Illustration
