Question 6 (1 point) A car slows down and comes to a stop at a red light What happensto its momentum? It increases but it stays the same b It goes to 0 going away as it slows down It goes to 0 transferring to the road/Earth It goes to 0 transferring to other forms of energy

Explicación
## Step 1Momentum is a physical quantity that represents the quantity of motion an object has. It is calculated by multiplying the mass of the object by its velocity. ### **Momentum = mass \times velocity**## Step 2When a car slows down and comes to a stop, its velocity decreases. Since the mass of the car remains constant, the momentum of the car will decrease as the velocity decreases.## Step 3When the car comes to a complete stop, its velocity is zero. Therefore, the momentum of the car also becomes zero.## Step 4The momentum of the car does not transfer to the road or Earth, nor does it transfer to other forms of energy. The momentum simply decreases to zero as the car slows down and stops.
