Transcript

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