Before you watch the video, give your answer here... and why you think it's correct.

So they should roll equally fast.

(The correct answer is that it depends)
Yes, the weight of the bottle does affect its speed rolling downhill. Objects with more mass have more inertia, which means they are harder to start or stop moving. Therefore, a heavier bottle will have a slower speed rolling downhill compared to a lighter bottle.
Yes, the shape of the bottle can impact its speed rolling downhill. Objects with a streamlined shape, such as a water bottle, experience less air resistance and therefore can reach higher speeds compared to objects with a bulkier shape, such as an ice bottle.
Yes, the surface the bottle is rolling on can affect its speed. A smoother surface will allow the bottle to roll faster, while a rougher surface will cause more friction and slow down the bottle's speed.
Yes, the temperature of the bottle can affect its speed rolling downhill. A bottle of ice will melt as it rolls downhill, which can create a layer of water between the bottle and the surface, reducing friction and allowing the bottle to roll faster.
Yes, the angle of the slope can impact the speed of the rolling bottle. A steeper slope will result in a faster descent for the bottle, while a flatter slope will slow down the bottle's speed.
