The velocity of a car goes from 0 m/s to 60 m/s in a forward direction. What is the best explanation for this change?

Question 10 options:

When the speed was 0 m/s, the forces acting on the car were unbalanced. When the forces became balanced, the car started to move.


When the velocity was 0 m/s, all the forces acting on the car were balanced. The velocity changed because at least one unbalanced force is acting on the car.


When the inertia was constant, the speed was 0 m/s. The speed changed because the inertia of the car increased.


The force of gravity on all sides was equal at 0 m/s. The velocity of the car increased because the force of gravity on the back of the car increased.
