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
- 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).
- 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.
- 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.
- Can work be negative? Yes, work can be negative when the force applied is in the opposite direction of the object's displacement.
