how much work is being done if a 100 N box is lifted 3 meters off the ground???
100 x 3 = 300 Joules.
To calculate the work done in lifting a box, you need to know two things: the force applied and the displacement. The formula to calculate work is given by:
Work = Force x Displacement x cos(theta)
Where:
- Work is the amount of work done (measured in joules, J)
- Force is the force applied (measured in newtons, N)
- Displacement is the distance over which the force is applied (measured in meters, m)
- Theta (θ) is the angle between the force vector and the direction of displacement. In this case, we assume lifting the box vertically, so theta is 0 degrees, and cos(0) is equal to 1.
Given:
- Force = 100 N
- Displacement = 3 m
- Theta (θ) = 0 degrees
Using the formula, we can calculate the work done as:
Work = 100 N x 3 m x cos(0)
Work = 100 N x 3 m x 1
Work = 300 J
Therefore, the work done in lifting the 100 N box 3 meters off the ground is 300 joules.
