Work done by a force is calculated as the product of the force and the distance over which it acts, in the direction of the force. Formula: Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of movement.

FAQs & Answers

  1. What is the formula for calculating work done by a force? The formula for calculating work done by a force is Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of movement.
  2. How does the angle affect the work done by a force? The angle θ affects the work done because it determines the component of the force that acts in the direction of movement. If θ is 0 degrees, all the force contributes to the work done; if θ is 90 degrees, no work is done.
  3. What units are used to measure work? Work is measured in joules (J) in the International System of Units (SI), where 1 joule equals the work done when a force of one newton moves an object one meter in the direction of the force.
  4. Can work be done if there is no movement? No, work cannot be done if there is no movement in the direction of the applied force. If an object does not move, regardless of how much force is applied, the work done is zero.
