To calculate work done by tension: Use the formula Work = Tension × Distance × cos(θ), where Tension is the force applied, Distance is the displacement of the object, and θ is the angle between the direction of the tension force and the displacement. For example, if a rope applies 50N to move an object 10m horizontally, and the rope is parallel to the movement, then Work = 50N × 10m × cos(0) = 500 Joules.
FAQs & Answers
- What is the formula for calculating work done by tension? The formula for calculating work done by tension is Work = Tension × Distance × cos(θ), where Tension is the force applied, Distance is the displacement of the object, and θ is the angle between the direction of the tension force and the displacement.
- How do you find the work done if the tension is perpendicular to the direction of movement? When the tension is perpendicular to the direction of movement (θ = 90°), the work done is zero because cos(90°) = 0. Therefore, Work = Tension × Distance × cos(90°) = 0.
- Can you give an example of calculating work done by tension? Certainly! For instance, if a rope applies a tension of 50N to move an object 10m horizontally and the rope is parallel to the movement, then the work done is Work = 50N × 10m × cos(0) = 500 Joules.
- What units are used for measuring work done? Work is measured in Joules (J), which is defined as the amount of energy transferred when a force of one newton displaces an object by one meter in the direction of the force.
