5.2.1 Calculating Work Done

Cards (46)

  • The amount of work done depends only on the force applied and the displacement of the object.
    False
  • Work done is maximized when the angle between the force and the displacement is 0
  • Match the variable with its symbol and unit:
    Work Done ↔️ W, Joules (J)
    Force ↔️ F, Newtons (N)
    Displacement ↔️ d, Meters (m)
  • If the force is doubled, the work done is also doubled.

    True
  • Work done is the energy transferred when a force moves an object through a displacement
  • Arrange the factors affecting work done from most to least significant when the force and displacement are in the same direction.
    1️⃣ Force applied
    2️⃣ Displacement of the object
    3️⃣ Angle between force and displacement
  • When the force and displacement are perpendicular, no work is done.

    True
  • Work done is the energy transferred when a force moves an object through a displacement
  • Arrange the steps to calculate work done using the formula W = F × d.
    1️⃣ Identify the force (F)
    2️⃣ Identify the displacement (d)
    3️⃣ Apply the formula W = F × d
    4️⃣ Include the unit joules (J)
  • A greater force or displacement results in less work done.
    False
  • What is work done measured in?
    Joules
  • Displacement is the distance the object moves in the direction of the force
  • How much work is done if a force of 50 N moves a box 3 meters?
    150 J
  • The force in work done calculations is measured in newtons.

    True
  • What are the values of force and displacement in the statement: "A force of 200 N moves a crate 5 meters"?
    F = 200 N, d = 5 m
  • Work done is measured in joules
  • How much work is done if a force of 100 N moves an object 5 meters?
    500 J
  • Doubling the force doubles the work done
  • Work done is minimized when force and displacement are perpendicular.

    True
  • The formula W = F × d represents the relationship between work done, force, and displacement
  • Force is measured in newtons
  • If a force of 50 N pushes a box 3 meters along the floor, the work done is 150 joules.
  • Steps to identify force and displacement from a problem statement:
    1️⃣ Look for a quantity in newtons (N) for force.
    2️⃣ Look for a quantity in meters (m) for displacement.
  • Work Done (W) is measured in joules
  • Match the variable with its description:
    Work Done ↔️ Energy transferred when a force moves an object
    Force ↔️ The amount of push or pull
    Displacement ↔️ Distance moved in the direction of the force
  • The formula W = F × d represents the relationship between work done, force, and displacement
  • Force is measured in newtons (N)

    True
  • What happens to work done when the force is increased?
    Increases
  • Match the variable with its symbol and units:
    Work Done ↔️ W, Joules (J)
    Force ↔️ F, Newtons (N)
    Displacement ↔️ d, Meters (m)
  • The displacement in work done calculations is measured in meters
  • What is the formula for work done?
    W = F × d
  • Force is measured in newtons.
    True
  • Factors affecting work done in order of relevance
    1️⃣ Force applied
    2️⃣ Displacement of the object
    3️⃣ Angle between force and displacement
  • What angle between force and displacement maximizes work done?
    0 degrees
  • How much work is done if a force of 50 N pushes a box 3 meters?
    150 J
  • Work done is measured in joules (J).

    True
  • A greater force or displacement results in more work being done.

    True
  • Match the variable with its symbol and units:
    Work Done ↔️ W (Joules)
    Force ↔️ F (Newtons)
    Displacement ↔️ d (Meters)
  • In the example "A force of 200 N moves a crate 5 meters," the force is 200 N.
  • The formula to calculate work done is W = F × d.
