Q.1
What forces are exerted by magnets?
  • Pushes
  • Pulls
  • Pushes and pulls
  • Neither pushes nor pulls
Q.2
When a bowl is sitting on a table, which forces are said to be 'balanced'?
  • Gravity and air resistance
  • Upthrust and gravity
  • Friction and magnetism
  • Magnetism and air resistance
Q.3
Why do trainers have rough-textured soles?
  • Rough-textured soles make trainers more 'slippery'
  • No one wants shoes which don't leave interesting footprints
  • Rough-textured soles help trainers to 'grip' surfaces better
  • People like to show off their shoe soles
Q.4
Different Newtonmeters are used to measure different amounts of force. A Newtonmeter designed to measure large forces will have what type of spring?
  • A long, thin, very flexible spring
  • A thick spring that is very stiff
  • A short, but very flexible spring
  • No spring
Q.5
Which of these objects is designed to have low friction?
  • Skis
  • Car tires
  • Bicycle brakes
  • Carpet
Q.6
What effect does air resistance have on a falling object?
  • It causes the falling object to speed up
  • It pushes the falling object sideways
  • It has no effect
  • It slows the falling object down
Q.7
What does friction cause?
  • Wind
  • Upthrust
  • Heat
  • Gravity
Q.8
If an object is stationary (not moving), what are the forces acting on it?
  • The forces are balanced
  • The forces are unbalanced
  • The forces are moving
  • The forces are unmoving
Q.9
Which of these would be a result of applying force to a material?
  • The material is stretched
  • The material is compressed
  • The material is twisted
  • The material is changed into a new material
Q.10
'Compressing' a spring means which of these?
  • To push it inwards
  • To pull it outwards
  • To tie it into a knot
  • To send it down the stairs
