What is the work done in moving an object from a point A to point B in a uniform gravitational field?
  1. Depends on the path taken
  2. Zero
  3. Depends on the mass of the object
  4. Depends on the height difference

Questions & Step-by-Step Solutions

What is the work done in moving an object from a point A to point B in a uniform gravitational field?
  • Step 1: Understand that a uniform gravitational field means the force of gravity is constant.
  • Step 2: Identify the two points: Point A (starting point) and Point B (ending point).
  • Step 3: Measure the height of Point A above a reference level (like the ground).
  • Step 4: Measure the height of Point B above the same reference level.
  • Step 5: Calculate the height difference by subtracting the height of Point A from the height of Point B.
  • Step 6: Use the formula for work done: Work = Weight x Height Difference.
  • Step 7: Remember that Weight = Mass x Gravitational Acceleration (approximately 9.81 m/s²).
  • Step 8: Plug in the values to find the work done in moving the object from Point A to Point B.
