Calculating power in everyday activities is really easy!

1. Basic Formula: Power ($P$) is all about how much work ($W$) you do in a certain amount of time ($t$). Here’s the simple formula:

   $P = \frac{W}{t}$

2. Example 1: Let’s say you lift a backpack that weighs 20 kg. To find out how much work you did, we use the formula $W = m \cdot g$, where $g$ (the force of gravity) is about 9.8 meters per second squared. If you lift the backpack to a height of 2 meters in 4 seconds, here’s how you can figure it out:

   • Work done: $W = 20 \times 9.8 \times 2 = 392 \text{ J}$ (Joules)
   • Power: $P = \frac{392}{4} = 98 \text{ W}$ (Watts)

3. Example 2: Now, let’s think about jogging. If you jog for 10 minutes (which is 600 seconds) and do 3000 Joules of work, you can find the power like this:

   • $P = \frac{3000}{600} = 5 \text{ W}$

So next time you’re doing something like lifting or jogging, just remember this formula! You can see how power works in your daily life!
