To figure out how much work is done in our daily lives, you can use this simple formula:

$W = F \cdot d \cdot \cos(\theta)$

Here's what each letter means:

• $W$ = Work done (measured in joules)
• $F$ = Force used (measured in newtons)
• $d$ = Distance moved (measured in meters)
• $\theta$ = Angle between the force and the direction you move

Everyday Examples:

1. Lifting something:

   • Force: the weight of the item (for example, a 10 kg object weighs about 98 N)
   • Distance: how high you lift it (for example, 2 m)
   • Work Done:
     $W = 98 \cdot 2 \cdot \cos(0) = 196 \text{ J}$

2. Pushing a box:

   • Force: 50 N
   • Distance: 5 m
   • Angle: 0° (pushing straight forward)
   • Work Done:
     $W = 50 \cdot 5 \cdot \cos(0) = 250 \text{ J}$

By understanding these ideas, you can easily calculate work done in different daily activities.
