When we think about the work we do every day, it can actually be really interesting!

In simple physics terms, work is calculated with this formula:

Work = Force × Distance

Let’s look at some everyday examples to see how this works:

1. Lifting Objects

• Example: Picking up a backpack.
  • Imagine you lift a 10 kg backpack from the ground to your waist, which is about 0.5 meters high.
  • The force used here is from gravity. Gravity pulls at a strength of about 9.8 N for every kg.
  • So, for the backpack, the total force is:
    • 10 kg × 9.8 N/kg = 98 N.
  • The work done in lifting the backpack is:
    • 98 N × 0.5 m = 49 J.

2. Pushing Furniture

• Example: Moving a sofa.
  • If you push a sofa with a force of 50 N for 2 meters, the work you do is:
    • Work = 50 N × 2 m = 100 J.

3. Walking Up a Hill

• Example: Hiking up a slope.
  • If you're hiking up a hill that is 10 meters high using a force that’s about the same as your weight (let’s say 600 N), the work you do is:
    • Work = 600 N × 10 m = 6000 J.

4. Riding a Bike

• Example: Pedaling your bike.
  • When you pedal your bike, you push against some resistance to move forward. If you use a force of 100 N to go 5 meters, the work done is:
    • Work = 100 N × 5 m = 500 J.

These examples show that work is everywhere! Whether we’re lifting, pushing, or just moving around, we are always doing work. It’s pretty cool to see how physics is part of our daily activities!
