Whoa, did you feel that sudden jolt when the bus slammed on the brakes, Alex? It's like some invisible force pulled us backward. |
|
|
Yeah, it was kind of awful but oddly fascinating, Bailey. I think it's connected to the whole motion and force thing. |
|
|
Motion and force? |
|
|
Yeah, I believe it's related to the law of inertia. Remember that physics class? The one where Mr. Thompson explained it? |
|
|
Oh, I remember now! Inertia is where objects in motion want to stay that way, unless a force causes them to change speed and direction, right? |
|
|
Spot on! When the bus stopped, our bodies wanted to keep moving forward because of the inertia. |
|
|
Ah, now it's coming back to me. Newton's first, second and third laws! |
|
|
You know, it's not just when the bus stops. When it starts, thers's this sudden pull backward. Ever notice that? |
|
|
Yeah, thinking about what we just talked about, it must be related to the law of inertia again. |
|
|
Exactly! When the bus starts, our bodies want to stay at rest, but the bus is moving. So there's this sudden change, and we feel the jerk. |
|
|
Oh, I see. It's fascinating how you can feel physics in action during a bus ride, with all the forces and motion playing out. |
