  • Applied force
  • Gravity force
  • Normal force
  • Friction force
  • Air resistance force
  • Tension force
  • Spring force
• Applied force (Fapp)


  A force that is applied by a person or another object
• Gravity force (F)


  A downward force that pulls towards the center of the earth
• Normal force (Fn)


  An upward force/support force exerted upon an object that is in contact with another stable object
• Friction force (FF)


  The force exerted by a surface on an object moving across it
• Air resistance force (Fair)


  A special type of frictional force that acts upon objects as they travel through the air
• Tension force (Ft)


  A force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite sides
• Spring force


  The force exerted by a compressed or stretched spring upon any object that is attached to it
