Questions & Step-by-Step Solutions

If a force of 15 N is applied to move an object 4 m, how much work is done?
  • Step 1: Identify the force applied to the object, which is 15 N (Newtons).
  • Step 2: Identify the distance the object is moved, which is 4 m (meters).
  • Step 3: Use the formula for work, which is Work = Force × Distance.
  • Step 4: Substitute the values into the formula: Work = 15 N × 4 m.
  • Step 5: Calculate the result: 15 × 4 = 60.
  • Step 6: The work done is 60 J (Joules).
  • Work – Work is defined as the product of the force applied to an object and the distance over which that force is applied.
