Question:

Which object has more kinetic energy: an 800 kg car moving at a velocity of +20 m/s, or an 800 kg car moving at a velocity of -20 m/s?

The car going +20 m/s has more kinetic energy

The car going -20 m/s has more kinetic energy

The two cars have the same amount of kinetic energy

We can’t tell which one has more kinetic energy without knowing the force on the cars
