Post Hovercraft Inertia Lab

Post Hovercraft Blog Post

a.) Riding on a hovercraft feels like you are floating, and as you glide, you are in a frictionless environment and your velocity stays that same, making the gliding continue at the speed you are going. Riding a sled or a skateboard is different because when riding those objects, you can pick up speed, but eventually your speed will decrease and you will come to a stop because of the friction. Unlike riding a sled or skateboard, the hovercraft continues at a constant speed and never stops or slows down unless a force intervenes.

b.) The hovercraft helps demonstrate inertia is the sense that the hovercraft had to be pushed out of its state of rest to start moving, and the only way to slow it down was to use force and stop it, putting it in a state of rest. The hovercraft also demonstrated equilibrium when the net force equaled 0N in two situations: it was moving at a constant velocity or when it was at rest.

c.) In the hovercraft lab, acceleration was demonstrated when someone was pushing the hovercraft or when someone was stoping the hovercraft. In these situations, the hovercraft was speeding up in the beginning and slowing down when stopped.

d.) In the lab, after being pushed off, the hovercraft was in a frictionless environment, thus making it so that it would continue at a constant velocity. The speed stayed that same, and would have continued to stay the same if a force had not stopped it (the force in this situation being the person who stopped the hovercraft).

e.) During the hovercraft lab, some members of the class were harder to start and stop than others, this being because people with more mass have more inertia, therefore they are harder to get started because the state they are in of either rest or motion wants to continue being in this state.

  1. I liked how organized you made this post. The organization not only made the blog post look better, but it also made it much neater and easier to break down the questions and answers. Our posts were similar in the sense that we both had a very similar explanation of equilibrium displayed in this lab. Our posts are different because of the simple fact that yours went into much greater detail than mine, further explaining each concept. Great job!
