Work, Force, Distance, Energy

• What is the definition of work done?

  Work done occurs when a force moves an object
• What happens to work done when the angle θ is 90°?

  Work done is zero
• What does the variable F represent in the work done formula?

  Applied force
• What happens to work done when the distance moved increases?

  Work done increases with greater distance
• If you lift a box a shorter distance, what happens to the potential energy transferred?

  Less potential energy is transferred
• What happens when you do work on an object?

  You transfer energy to it
• How does pushing a ball relate to energy transfer?

  Your effort gives the ball kinetic energy
• How does lifting a heavy backpack compare to a lighter one in terms of work done?

  • Lifting a heavy backpack requires more work
  • Lifting a lighter backpack requires less work
  • Both are lifted the same distance
• What does the variable θ represent in the work done formula?

  Angle between force and displacement
• How does pushing a box across different distances affect work done?

  • Pushing across a longer distance requires more work
  • Pushing across a shorter distance requires less work
  • Force remains the same in both cases
• How does displacement relate to the concept of work done?

  Displacement is necessary for work to occur
• How does the $\cos \theta$ term affect work done?


  Work is done only when force aligns with movement
• What is the formula for work done?

  $W =$$F \cdot d \cos \theta$
• How does the angle of force application influence the efficiency of work done?

  Smaller angles increase work efficiency
• How does applying a stronger force affect work done?

  It increases the amount of work done
• What does the variable d represent in the work done formula?

  Distance moved in the direction of force
• How does distance affect energy transfer when doing work?

  A longer distance means more energy is transferred
• What type of energy is transferred when lifting a heavy box higher?

  More potential energy is transferred
• If a box is pushed with a force of 20N over 5m at an angle of 0°, what is the work done?

  100J
• What does work done equal in terms of energy?

  Work done equals energy transferred
• What happens if the grocery cart doesn't move when pushed?

  No work is done due to no displacement
• How does the strength of the force affect energy transfer?

  A stronger force means more energy is transferred
• What does the variable W represent in the work done formula?

  Work done
• What is the relationship between work done, force, and distance?

  Work done is directly proportional to force and distance
• If the angle of force applied is 30°, how does it affect the work done compared to 0°?

  Work done is slightly less
