2.1.4 Mechanical advantage and disadvantage

• 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
