“FRICTION”

I. Learning Objectives At the end of the lesson, 95% of the fourth year students should be able to: 1. define friction; 2. identify the types of friction; 3. draw the free body diagram of forces in a given problem; and 4. determine the advantages and disadvantages of frictional force in our daily life.

II. Learning Content A. Subject matter Friction 1. Content outline
Definition of terms
Types of friction
Construction of free-body diagrams

B. Science Concepts 1. Friction or frictional force (Ff or Ffr ) is the force between surfaces in contact that resist their relative motion. 2. Static friction is the type of friction that occurs between bodies in contact which is at rest. 3. Kinetic friction occurs between bodies in contact which is in sliding motion. 4. Rolling friction occurs between bodies in contact that are in rolling motion. 5. Weight is the force directed towards the center of the earth which is perpendicular to the horizontal ground or surface. 6. Applied force is the push or pull applied to any object. 7. Normal force is the force that equals the force of gravity to keep an object in the surface it is situated.

C. Science Process Skills 1. Observing 2. Identifying variables 3. Inferring 4. Analyzing

D. Value Focus 1. Perseverance 2. Hard work 3. Valuing life

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely, the life sciences and the physical sciences. The life sciences include biology, zoology and botany. The physical sciences branch into areas such as geology, astronomy, chemistry and physics. However, physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion, forces, heat, sound, light…

SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed, but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of…

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides, the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet…
