Question

which of the following bottles are accelerating? select all that apply.
a bottle of formula that is rolling at a constant speed directly away from a baby
a bottle of ketchup that is curving to the left as it is passed around a table
a bottle of shampoo that is moving downward with decreasing speed as a store employee places it on a shelf

Explanation:

Acceleration occurs when an object changes its speed, direction, or both.

1. A bottle rolling at constant speed in a straight line has no change in speed or direction, so it does not accelerate.
2. A ketchup bottle curving left is changing direction, which means it is accelerating.
3. A shampoo bottle with decreasing downward speed is changing its speed (slowing down), which means it is accelerating.

Answer:

• B. a bottle of ketchup that is curving to the left as it is passed around a table
• C. a bottle of shampoo that is moving downward with decreasing speed as a store employee places it on a shelf
