Answer to Question #242895 in Physics for rshiii

Question

1. A car has the same kinetic energy when it is traveling south at 30 m/s as when it is traveling northwest at 30 m/s. Is the momentum of the car the same in both cases? Explain

Answer 1

The momentum of the car is different because it is a vector quantity (unlike scalar energy) meaning that momentum is described by magnitude and direction. In our scenario, the direction is different, so is the momentum.
