In physics, work means the energy used when a force moves something over a distance.

But work isn't just about moving an object. The force needs to push or pull in the same direction as the movement.

For example, if you push a box across the floor, you are doing work!

How to Measure Work:

1. Formula: To find out how much work is done, you can use this formula:

   W = F × d × cos(θ)

   Here's what the letters mean:

   • W is the work done
   • F is the force you apply
   • d is how far the object moves
   • θ is the angle between the force and the direction the object moves.

2. Units: In the International System of Units (SI), the unit for work is called a joule (J).

   One joule is equal to one newton meter. This means if you use a force of one newton to move something one meter, you have done one joule of work!
