To calculate work done, use the formula: Work Done = Force x Distance x cos(θ). Force is measured in Newtons (N), Distance in meters (m), and θ is the angle between the force and the direction of motion. For example, if you push a box with a force of 10 N for 5 meters, and the force is applied in the direction of motion (θ=0), the work done is: 10 N x 5 m = 50 Joules.
FAQs & Answers
- What is the formula for calculating work done? The formula for calculating work done is Work Done = Force x Distance x cos(θ), where Force is in Newtons, Distance is in meters, and θ is the angle between the force and the direction of motion.
- What are the units used to measure work done? Work done is measured in Joules (J), where 1 Joule is equal to 1 Newton meter (N·m).
- How do you calculate work done when the force is applied at an angle? To calculate work done when the force is applied at an angle, you should use the formula: Work Done = Force x Distance x cos(θ). Here, θ is the angle between the force and the direction of motion.
- Can work be negative? Yes, work can be negative if the force acts in the opposite direction to the motion. This occurs when the angle θ is greater than 90 degrees.
