In the helium balloon inside the car example, what was the conclusion the class reached as to why this did not violate the first law?

https://www.youtube.com/watch?v=XXpURFYgR2E

The air inside the car had a greater mass than the air in the balloon. This air moved as predicted by the first law. Since the air outside the balloon had less mass it forced the balloon with more mass to go in the opposite direction.

The air inside the car had a greater mass than the air inside the balloon. This air moved as predicted by the first law. Since the air outside the balloon had more mass it forced the balloon with less mass to go in the opposite direction.

The class decided that it did violate Netwon's First Law, because anything can violate a law of Physics.

The _______ is the vector _______ of all the _______ that act upon an object.

Why does constant velocity indicate NO net force?

for something to be moving at a constant velocity means there must be a force acting upon it somewhere (Mr. Fischers Example of the Laptop Case)

net forces are connected to velocity, not acceleration

constant velocity means no acceleration, and for there to be a net force there must be acceleration

constant velocity means that there is acceleration, and therefore means that there is no net force

Explain what is happening to the object using the word 'acceleration'.

Explain what is meant by 'terminal velocity.

Terminal velocity is when fair becomes greater than fgrav and then the net force or acceleration on the object increases.

Terminal velocity is when fgrav and fair become equal and then there ceases to be any net force or acceleration on the object.

Terminal velocity is when net force and fair become equal and then there ceases to be any fgrav on the object.
