Understanding Kinetic Energy
Kinetic energy (KE) is the energy an object possesses due to its motion. It's calculated using the following formula:
KE = (1/2) * m * v²
Where:
* KE = Kinetic Energy (measured in Joules (J))
* m = mass (measured in kilograms (kg))
* v = velocity (measured in meters per second (m/s))
The Calculation
1. Identify the values:
* m = 2000 kg
* v = 25 m/s
2. Plug the values into the formula:
KE = (1/2) * 2000 kg * (25 m/s)²
3. Calculate:
KE = 1000 kg * 625 m²/s²
KE = 625,000 J
Answer: The kinetic energy of the bus is 625,000 Joules.
