							QUESTIONS
1. What is a force? Can we see them?
2. What can forces do to an object?
3. What factors affect the amount of force needed to move an
   object?
4. What happens if the forces acting on an object are (a)
   balanced and (b) unbalanced?
5. What is friction?
6. Think of three ways in which friction can (a) be useful and (b)
   be a nuisance.
7. What does gravity do?
8. What is the size of a force measured in?
9. Magnetic force does not have to touch an object to make it
   move. Can you think of another force that can do this?

FIND OUT
i.    The unit used to measure the size of a force is named after
      a famous scientist. Write a paragraph about him.
ii. Magnets only attract certain metals. Find out which ones.
iii. Magnets have two areas on them where the magnetic
      force is strongest. What are these areas called?
iv. Two magnets can attract or repel. What do these words
      mean?
v. When something starts to move it accelerates. What does
      this mean?
vi. Another kind of friction is called drag. What is this exactly?
vii. Streamlining reduces drag. What is this?
viii. Draw a picture of yourself throwing a netball or kicking a
      football. Draw a pair of force arrows to show the direction
      and size of the forces acting on the ball.
