P6 Forces

  1. 1. Forces
  2. 2. Going Back … <ul><li>A force is a PUSH or a PULL </li></ul><ul><li>Forces cannot be seen </li></ul><ul><li>How do we know they exist? </li></ul>
  3. 3. The Effects of a Force <ul><li>It can make a stationary object move </li></ul><ul><li>It can make a moving object speed up </li></ul><ul><li>It can change the direction a of a moving object </li></ul><ul><li>It can slow down a moving object </li></ul><ul><li>It can stop a moving object </li></ul><ul><li>It can change the shape of an object </li></ul>
  4. 4. Different Types of Forces <ul><li>Gravitational force (gravity) </li></ul><ul><li>Elastic spring force </li></ul><ul><li>Frictional force (friction) </li></ul><ul><li>Magnetic force </li></ul>
  5. 5. Gravitational Force <ul><li>Is there a force acting on the ball? </li></ul><ul><li>Is the force of attraction a push or a pull? </li></ul><ul><li>Will an object have any weight if there is no gravitational force acting on it? </li></ul>
  6. 6. Elastic Spring Force <ul><li>What happens to the spring after it is compressed or stretched, then released? </li></ul><ul><li>Is the rubber band elastic? </li></ul><ul><li>Is the modelling clay elastic? </li></ul>
  7. 7. Frictional Force <ul><li>Why did the coin slow down and stop? </li></ul><ul><li>Friction is greater when on object is an a rough surface </li></ul><ul><li>In what ways is friction useful to us? </li></ul><ul><li>Friction can produce heat </li></ul>
  8. 8. Magnetic Force (P3 Revision) <ul><li>Magnetic force of attraction </li></ul><ul><li>Magnetic force of repulsion </li></ul><ul><li>Attraction -> pull </li></ul><ul><li>Repulsion -> push </li></ul>
