1. Was your hypothesis correct? Why or why not? 2. Use the experiment to explain what density is. How is it different from weight and mass?

3. Why do some objects with a greater mass float and some objects with less mass sink?

4. As a scientist, you have been tasked with building a boat. Your first prototype sinks. What can you do to make it float?

5. What did you learn from this lab?

What even is this. where is the question

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
