Example 1
easyA person pushes a box with a force of over a distance of in the direction of the force. How much work is done?
Solution
- 1 Because the force is in the same direction as the displacement, use .
- 2 Substitute the values: .
- 3
Answer
Work is done when a force causes displacement. When force and displacement are in the same direction, work equals force times distance.
