📌 Understanding Kinetic Energy
Kinetic energy is the energy of motion. It is calculated using:
Kinetic Energy (KE) = 1/2 × Mass (m) × Velocity² (v²)
The unit of kinetic energy is **Joule (J)**.
📌 Examples of Kinetic Energy Calculation
| Mass (kg) | Velocity (m/s) | Kinetic Energy (J) |
|---|---|---|
| 10 | 5 | 125 |
| 15 | 8 | 480 |
| 20 | 12 | 1440 |
❓ FAQs
Q1: How do I calculate kinetic energy?
✅ Kinetic energy is calculated using the formula **KE = 1/2 × m × v²**, where m is mass and v is velocity.
Q2: What is the unit of kinetic energy?
✅ The unit of kinetic energy is the **Joule (J)**, which is equivalent to one Newton-meter (N·m).
Q3: Can kinetic energy be negative?
✅ No, kinetic energy is always positive because it depends on the square of velocity.
Q4: How does velocity affect kinetic energy?
✅ Kinetic energy increases quadratically with velocity, meaning if velocity doubles, kinetic energy increases four times.
Q5: What happens to kinetic energy when mass increases?
✅ Kinetic energy increases linearly with mass, meaning doubling the mass doubles the kinetic energy.
