Work Done vs Force
Formel
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.
Lösungsbeispiel
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
Häufig Gestellte Fragen
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.
