Work Done vs Force
सूत्र
## Work Done by a Force Work is the energy transferred when a force moves an object through a displacement. ### Formula **W = F * d * cos(theta)** When the force is parallel to motion (theta = 0), all of the force contributes to work. At 90 degrees, no work is done.
हल किया गया उदाहरण
A 50 N force pushes a box 10 meters along the floor (angle = 0 degrees).
- 01W = F * d * cos(theta)
- 02W = 50 * 10 * cos(0°)
- 03W = 50 * 10 * 1
- 04W = 500 J
अक्सर पूछे जाने वाले प्रश्न
Can work be negative?
Yes. When the angle between force and displacement exceeds 90 degrees, cos(theta) is negative, and the force removes energy from the object (e.g., friction).
What is the unit of work?
Work is measured in joules (J). One joule equals one newton-meter.
Is work a scalar or vector?
Work is a scalar quantity. It has magnitude but no direction, even though it is calculated from vector quantities.
