📌 Understanding Power (Watts)
Power is the rate at which work is done over time. It is calculated using:
Power (P) = Work Done (W) / Time (t)
The unit of power is **Watt (W)**, where 1 Watt is equal to **1 Joule per second (J/s)**.
📌 Examples of Power Calculation
| Work Done (J) | Time (s) | Power (W) |
|---|---|---|
| 100 | 5 | 20 |
| 250 | 10 | 25 |
| 500 | 20 | 25 |
❓ FAQs
Q1: How do I calculate power?
✅ Power is calculated using the formula **P = W / t**, where W is work done and t is time.
Q2: What is the unit of power?
✅ The unit of power is the **Watt (W)**, which is equivalent to one Joule per second (J/s).
Q3: Can power be negative?
✅ Yes, power can be negative in cases where energy is being dissipated, such as in friction or resistance.
Q4: How does time affect power?
✅ Power is inversely proportional to time. If time increases while work remains constant, power decreases.
Q5: What happens to power if work increases?
✅ Power increases proportionally with work. If work done doubles, power also doubles.
