Question:
A car and a bicycle are both moving at the same speed. The car has a much greater mass than the bicycle. Describe how the kinetic energy of the car compares to the kinetic energy of the bicycle and explain why.
✅ Answer:
The car has more kinetic energy than the bicycle because kinetic energy depends on both mass and speed. Since both the car and the bicycle are moving at the same speed, the greater mass of the car results in higher kinetic energy.
💡 Explanation:
- Kinetic energy is calculated using the formula KE = 1/2 mv^2, where m is mass and v is speed.
- With both moving at the same speed, the object with the greater mass (the car) will have more kinetic energy.
