Mechanics

• 1 mark questions on making suvat models more realistic:

  • wind effect
  • more accurate value of gravity
  • including dimensions of the stone
• mark questions on making pulleys more realistic

  • The pulley is too smooth
  • rope being inextensible
  • balls being measured as particle
• if the stone (suvat) is subject to air resistance:

  • The value of U will be bigger
