What type of energy does a moving vehicle store depending on its mass and speed?
Active and passive safety
Explanation
**Kinetic energy** is the energy that a moving vehicle accumulates due to its **mass and speed**. This energy directly depends on the speed at which the vehicle is traveling.
- When a vehicle travels at **high speeds**, such as from 80 or 90 kilometers per hour, it consumes more fuel and pollutes more. This is because kinetic energy increases with speed, which requires more energy to maintain the vehicle's movement.
- The **Eco mode** in vehicles helps reduce fuel consumption by limiting the engine's power and speed. This also affects kinetic energy, as reducing speed decreases the energy accumulated by the vehicle.
- By **reducing speed** or stopping the vehicle, kinetic energy is decreased. This is achieved by lifting the foot off the accelerator and braking gently, allowing the vehicle to lose energy in a controlled manner.
In summary, kinetic energy is fundamental to understanding how a vehicle's speed and mass influence its fuel consumption and energy efficiency.
