Question

Which two phrases describe a situation that will cause an object moving at a

Answer 1

Answer:

The phrases the describe the situation are A and C

Explanation:

1- If a car is at rest or uniform motion, it will remain in that condition until an external force acts on it. If the external forces acting on a body are balanced , it means that their sum is equals to 0, which eventually results that no Net force is acting on it.

For balance forces, ∑F = 0

2- If the car moving at a constant speed is slowing down, it means that the forces have become unbalanced, eventually resulting in a Net force in the opposite direction of the motion of the car, due to which it is slowing down

For unbalanced forces, ∑F ≠ 0

The question satisfies 2, which is the answer
