A balloon floats inside a stopped car. When the car starts moving forward, the balloon appears to move backward relative to the car. Which statement best explains this observation?(1 point)
Responses
1.The car moves forward, while inertia keeps the balloon in place.
2.The motion of the car creates an unbalanced backward force on the balloon.
3.Inertia prevents the force of the car from acting on the balloon.
4.The force of inertia on the balloon balances the force from the motion of the car.
that is incorrect it is actually the first answer choice.
Well, I have to say, this is quite a funny situation we have here! It's like the balloon and the car are playing a game of "Opposite Day." But let's see if we can figure out what's going on scientifically.
Hmm, I'm going to have to eliminate option 1 because I don't think inertia can magically keep the balloon in place while the car is moving. Inertia is a little mischievous, but not that mischievous!
Option 2 suggests that the car's motion creates an unbalanced backward force on the balloon. Well, it's true that the air inside the car is also moving forward with the car, which creates some sort of force acting on the balloon. But is it really a backward force? I'm not so sure.
Option 3 brings in the concept of inertia again, suggesting that it prevents the force of the car from acting on the balloon. Well, inertia does have a habit of resisting changes in motion, but I'm not convinced it stops the force of the car from acting on the balloon.
Finally, we have option 4, which claims that the force of inertia on the balloon balances the force from the motion of the car. Ah, balance is always a good thing! It's like the yin and yang of forces. So, this explanation seems plausible to me.
Therefore, my dear friend, I'm going to go with option 4. The force of inertia on the balloon balances the force from the motion of the car. Now, I hope that answer didn't "inflate" any confusion!
The correct statement that best explains this observation is:
3. Inertia prevents the force of the car from acting on the balloon.
The correct statement to explain this observation is: Option 1 - The car moves forward, while inertia keeps the balloon in place.
When the car starts moving forward, the air and everything inside it, including the balloon, have a tendency to resist changes in their motion. This tendency is known as inertia. Since the balloon is filled with air, it is more buoyant than the surrounding air, which causes it to float.
When the car accelerates forward, the friction between the air molecules and the car causes the air inside the car to move forward with the car. However, because of the balloon's inertia, it resists moving forward with the car and stays in a relatively fixed position. As a result, when observed from inside the car, the balloon appears to move backward relative to the car's motion. This is because the car is moving forward, but the balloon is not moving forward at the same rate due to its inertia.
3. Inertia prevents the force of the car from acting on the balloon.
The balloon has inertia, which means it resists changes in its motion. When the car starts moving forward, the air inside the car (including the balloon) also moves forward with the car due to inertia. However, the balloon's inertia causes it to resist this forward motion and remain in place. As a result, it appears to move backward relative to the car.
