765 views

The basic formula for work done is: Work (W) = Force (F) × Distance (d). Here, work is measured in joules, force in newtons, and distance in meters. This formula calculates the amount of energy transferred when a force moves an object over a distance.

FAQs & Answers

  1. What units are used to measure work done? Work is measured in joules (J), which is the unit of energy in the International System of Units (SI).
  2. How do you calculate work done when force is applied at an angle? When force is applied at an angle, the work done can be calculated using the formula: Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.
  3. What is the difference between work and energy? Work is a measure of energy transferred when a force is applied to move an object, while energy is the capacity to do work.
  4. Can work be negative? Yes, work can be negative when the force applied is in the opposite direction of the object's displacement.
