ENGINEERING YOU CAN EXPLORE
What moves an electric car?
Look inside. Follow the energy. Take the wheel.
02 / FOLLOW THE ENERGY
Ready when you are. Press Drive to begin.
03 / TAKE THE WHEEL
Your rolling laboratory
Brake overrides the accelerator. Change one setting at a time for a fair test.
SCIENCE VIEW / GO ONE LEVEL DEEPER
Positive: energy leaving the battery.
Negative: energy returning.
Car + battery + passengers.
More mass needs more force to accelerate.
Energy of motion grows with the square of speed.
Gross driving use; recovered energy is shown separately above.
kW = power: how quickly energy is transferred. kWh = energy: how much is stored or used. A 40 kWh battery supplying 10 kW would last 4 hours in an ideal constant-power example.
Illustrative physics: rolling resistance, air drag, gravity, fixed drivetrain efficiency and limited energy recovery. Charging runs at 60× time. This is not a prediction for a real car.
