Basic physics

• Tension and Force


  Tension (T) = Force (F) / Length (L)
• Types of Forces


  Gravity, Friction, Normal force, Tension
• Tension example: Holding a beach ball


  Using a string or rope to apply force to control the movement of an object
• Tension examples


  Braking, Jumping rope, Suspension bridges
• Unit of Tension


  Newtons per meter (N/m) or Pascals (Pa)
• Measuring Tension


  Force meters or Spring scales
• Tension and Force (Exceptions)

  Tension is not always directly proportional to force; maximum breaking point is reached and tension decreases beyond that point
