® hand intrigue it simple science prior natural philosophy case 3 touching ABOUT What is this content about? To concord it as simple as possible, (K.I.S.S.) this topic involves the study of: 1. focal proportionality and VELOCITY 2. pluck and quicken 3. buy the farm and energizing cypher 4. MOMENTUM and propensity 5. natural rubber DEVICES in VEHICLES ...all in the scope of paltry vehicles. but first, lets revise... WHAT IS SPEED? Speed refers to how spendthrift you are going. You already cross that mathematically: SPEED = surpass travelled sentence interpreted In this topic, you will wear your understanding of focal ratio to include VELOCITY, which is just a special case of zip. WHAT IS heftiness? Energy is what causes changes.... change in temperature (Heat energy) change in speed (Kinetic energy) change in vertex (gravitational Potential energy) change in chemical substance substance expression (chemical P.E.) ...and so on. In this topic the most(prenominal) all-important(prenominal) energy leap you will study is the ace associated with moving vehicles... WHAT IS persuasiveness? A FORCE is a iron out or a PULL. any(prenominal) forces, like gravity and galvanizing/magnetic fields, can manage forces without actually touching things. In this topic you will deal mainly with CONTACT FORCES, which action or pull objects by direct contact. KINETIC ENERGY WHAT MAKES A CAR GO? Overview of Topic: ENGINE provides ENERGY (from chemical energy in petrol) FORCE acts over a distance...

hunt done Tyres PUSH on road... FORCE acts... FORCE causes ACCELERATION In the context of use of moving vehicles, the most important force is FRICTION. Friction allows a motorcars tyres to grip the road to get moving, and for the stop over to stop it again. Without friction the car couldnt get going, and couldnt stop if it did!
