  • Elasticity
  • Ductility
  • Malleability
  • Strength-to-weight ratio
• Strength

  The ability to withstand force
• Toughness

  The ability to withstand sudden impacts
• Brittleness

  The inability to withstand stress or deformation
• Hardness

  The ability to withstand scratches and wear
• Stiffness

  The ability to withstand bending under a load while still being able to keep its original shape
• Elasticity

  The ability to return to its original shape after deformation
• Ductility

  The ability to be deformed by stretching or bending
• Malleability

  The ability to be compressed or squeezed into shape
• Strength-to-weight ratio

  A measure of strength divided by the mass/weight of a material
• The different physical propertiesare:
