2.1.4 Mechanical advantage and disadvantage

Cards (22)

  • What is mechanical advantage (MA) defined as?
    Output force / Input force
  • A mechanical advantage less than 1 results in a smaller output force but increases range and speed
  • Mechanical disadvantage reduces the output force but increases the range and speed of movement.

    True
  • What is the role of a tennis racket in terms of mechanical advantage?
    MA greater than 1
  • What is the definition of mechanical advantage (MA)?
    Output force / Input force
  • When MA is less than 1, the output force is greater than the input force.
    False
  • Mechanical advantage greater than 1 reduces the task's difficulty by amplifying force.

    True
  • Steps to calculate mechanical advantage
    1️⃣ Divide output force by input force
  • Mechanical advantage greater than 1 makes tasks easier
  • What happens to the output force when the mechanical advantage is less than 1 in sports?
    It becomes smaller
  • Mechanical disadvantage occurs when the output force is smaller than the input force.

    True
  • A mechanical advantage greater than 1 amplifies the output force, making tasks easier.
    True
  • What is mechanical disadvantage defined as?
    MA less than 1
  • Match the mechanical advantage with its description and benefit:
    Greater than 1 ↔️ Output force > Input force, easier tasks
    Less than 1 ↔️ Output force < Input force, increased range and speed
  • Using a long-handled shovel results in a mechanical advantage greater than 1.
    False
  • A tennis racket is an example of mechanical advantage greater than 1
  • Match the mechanical advantage with its description and sports example:
    MA > 1 ↔️ Output force > Input force ||| Tennis racket
    MA < 1 ↔️ Output force < Input force ||| Long-handled shovel
  • What is the term for when the output force is smaller than the input force?
    Mechanical disadvantage
  • The mechanical advantage formula tells us how much the input force is amplified.
    True
  • Match the mechanical advantage with its description and benefit:
    Greater than 1 ↔️ Output force > Input force ||| Makes tasks easier
    Less than 1 ↔️ Output force < Input force ||| Increases range and speed
  • Rowing is an example of mechanical advantage greater than 1
  • What is the primary benefit of mechanical disadvantage in sports?
    Increased range and speed
