To find the work done by tension, use the formula W = F d cos(θ). Here, W is work, F is the tension force, d is the displacement, and θ is the angle between the force and displacement. First, measure the tension force (F) acting on the object. Next, determine the displacement (d) over which the force acts. Finally, find the angle (θ) between the tension force and the direction of displacement. Multiply these values and apply the cosine of the angle to get the work done by tension.

FAQs & Answers

  1. What is the formula for calculating work done by tension? The formula for calculating work done by tension is W = F d cos(θ), where W is work, F is the tension force, d is displacement, and θ is the angle between the force and displacement.
  2. How do you measure the angle when finding work done by tension? To measure the angle, determine the direction of the tension force and the direction of the displacement. Use a protractor or trigonometric methods to find the angle θ between these two directions.
  3. What factors affect the work done by tension? The work done by tension is affected by the magnitude of the tension force (F), the distance the object moves (d), and the angle (θ) between the force and the direction of movement.
  4. Can work done by tension be negative? Yes, the work done by tension can be negative if the angle θ is greater than 90 degrees, indicating that the tension force acts in the opposite direction to displacement.
