Questions & Step-by-Step Solutions

A 1 kg object is pushed with a force of 10 N over a distance of 3 m. What is the work done?
  • Step 1: Identify the force applied to the object, which is 10 N.
  • Step 2: Identify the distance over which the object is pushed, which is 3 m.
  • Step 3: Use the formula for work done, which is Work = Force × Distance.
  • Step 4: Substitute the values into the formula: Work = 10 N × 3 m.
  • Step 5: Calculate the result: 10 N × 3 m = 30 J.
  • Step 6: Conclude that the work done is 30 Joules.
  • Work – Work is defined as the product of force applied to an object and the distance over which that force is applied, measured in joules (J).
  • Force – Force is a vector quantity that causes an object to accelerate, measured in newtons (N).
  • Distance – Distance is a scalar quantity that represents the length of the path over which the force is applied, measured in meters (m).
