Transcript of "Forces"

  1. 1. What are they and what do they do?<br />Centripetal and centrifugal forces<br />
  2. 2. Centripetal force<br />When a roller coaster is moving through the loop on the track this force comes into play.<br />This is the force that causes an object to move in a circle.<br />
  3. 3. What is it?<br />A force which pulls an object toward the centre of a circle is called a centripetal force.<br />Centripetal force, is what makes an object move in a circular path.<br />When you swing a stone around on a string, you must pull on the string to keep the stone from flying off in a straight line. The pull the string applied to the object is centripetal force.<br />
  4. 4. Take as an example a stock car, <br />when it turns a corner the force that holds it on the track is the inward pull called centripetal force<br />
  5. 5. Centrifugal force<br />This is the force that is often used to describe why mud gets spun off a spinning tire, or water gets pushed out of the clothes during the spin dry cycle of your washing machine.<br />  <br />
  6. 6. What is it?<br />An object travelling in a circle behaves as if it is experiencing an outward force. <br />If the object is heavier, the force will be greater<br /> If the object is faster, the force will be greater<br /> And if the distance from the centre is greater the force will be greater too.<br />
  7. 7. We are all familiar with the effects of centrifugal force<br /> we experience it every time we are in a car and take a bend - we feel a force pushing us to the outside of the curve. <br />And if you have placed a cassette tape on the seat next to you when taking a sharp bend at speed, it slides across the seat.<br />
  8. 8. Centripetal force<br />Centrifugal force<br />This force is an inward pull<br />This force holds an object in a circle<br />This force is an outward pull.<br />This force pushes an object away from the circle<br />What’s the difference ?<br />
