Question

You use a horizontal force 25 Newtons N to push a box 3 meters to the right. Find the work you did.

W=Fed

Answer 1

Formula for work:

`w=Fd`

work(measured in joules) = force(measured in newtons) * distance(measured in meters)

__________________________________________________________

Given:

`F=25N`

`d=3m`

`w=?`

__________________________________________________________

Finding work:

`w=Fd`

`w=25*3`

__________________________________________________________

Answer:

`\fbox{w = 75 Joules}`

Answer 2

75 J

Step-by-step explanation:

You want the work done by a force of 25N over a distance of 3 m.

Work

As your formula tells you, the work is the product of force and distance:

W = Fd

W = (25 N)(3 m) = 75 N·m

Units

One newton·meter is one Joule.

= 75 J

Additional comment

Both newtons (N) and joules (J) are derived SI units:

1 N = 1 kg·m/s²

1 J = 1 kg·m²/s² = 1 N·m
