Which would most likely cause acceleration? check all that apply. flat road, wind, water movement, hill, or stop light.

wind

water movement

hill

stop light.

Explanation:

Remember that acceleration can be positive or negative, in this examples A stop light can create a negative acceleration because you need to hit te breaks in order to stop, wind and water movement and hill will cause the car to accelerate because of the going downhill and the effect of the water on the car, that would cause acceleration.

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
